2011-01-25	Marcus Meissner <marcus@jet.franken.de>

	* sierra-usbwrap.c: Instead of synthesizing USB Mass Storage protocol
          to send SCSI commands ... Use the usbscsi: port and send them
          directly.

2008-09-20	Marcus Meissner <marcus@jet.franken.de>

	* sierra.c: Implement storage_info function.

2007-04-22	Marcus Meissner <marcus@jet.franken.de>

	* *-desc.c: Removed "const" from some structures that 
	  are written to by the configuration handling code.

2007-02-13	Chandra Curtis <chandracurtis@ntu.edu.sg>
	*sierra.c, sierra-desc.h, olympus-desc.c: Added support for Olympus SP-500UZ.  
	(Works with gtkam, still some issue with gphoto2)

2006-08-08  Marcus Meissner  <marcus@jet.franken.de>

	* sierra.c: Added Nikon CoolPix 2100, from
	  Ken Restivo <ken@restivo.org>.

2005-09-26  Marcus Meissner  <marcus@jet.franken.de>

	* sierra-desc.c: Fixed 2 strict aliasing problems.

2005-08-04  Marcus Meissner  <marcus@jet.franken.de>
	
	* sierra.c: epson photopc 700 has no reg 51 either

2005-07-07  Marcus Meissner  <marcus@jet.franken.de>

	* sierra.c: Moved new Olympus entries prodid 0x109 here (from ptp2).

2005-06-10  Marcus Meissner  <marcus@jet.franken.de>

	* sierra.c: Added Nikon Coolpix 4300 in wrapper modce.

2005-05-30  Marcus Meissner  <marcus@jet.franken.de>

	* sierra.c: Sanyo VPC G250 does not have register 51.

2005-05-08  Marcus Meissner  <marcus@jet.franken.de>
	
	* sierra.c: The olympus c-420l does only like
	  speeds up to 57600.
	  The epson photopc 650 does only like up to 38400.

2005-02-27  Marcus Meissner  <marcus@jet.franken.de>

	Aurelien Jarno <aurelien@aurel32.net>
	* library.c: Increase buffer size to the one we will try to
	  to read. Newer libusb and kernels give more than 4k back to
	  read()s.

	  Debian bug#296708.

2005-02-16  Marcus Meissner  <marcus@jet.franken.de>
	
	* sierra.c: Added Pentax Optio 450. Thanks to Jack
	  for lending me his camera for some minutes. :)
	  (Capture works, but only if you plug it in with the lens
	   extracted already.)

2005-02-14  Marcus Meissner <marcus@jet.franken.de>
	* library.c, sierra-desc.h, sierra.c, sierra.h, sierra-usbwrap.c:
	  Nikon Coolpix * and Pentax cameras also support the Sierra 
	  protocol (usb wrapped), however with different command bytes.

	  This patch adds support to specify the usb wrapping camera
	  type and also adds the Nikon Coolpix 2500.

2005-01-22  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra-desc.c, sierra-desc.h: Add code in case we ever need a
	  GP_WIDGET_BUTTON/callback created, not currently used.

2005-01-05  Patrick Mansfield <patmans@users.sourceforge.net>
	* olympus-desc.c: Add other Olympus C750UZ camera settings, they
	  were using the C3040 ones except for the zoom. Also use
	  GP_WIDGET_MENU instead of GP_WIDGET_RADIO for the resolutions,
	  as the radio with many elements takes up to much space.

2005-01-04  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra-desc.c: Call gp_widget_set_name to properly set the
	  "name", so new gphoto2 --list-config and such are easier to
	  use.

2004-12-11  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra.c, sierra.h: Per report from Emmanuel Beranger, add and
	  use a SIERRA_MID_SPEED flag so we only use download speeds of
	  9600 to 38400 for the Olympus C820-L.

2004-07-30  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c, sierra.c, sierra.h: Patch from Sean Bruno
	  <sean.bruno@dsl-only.net> to support Toshiba cameras. Added and
	  use SIERRA_NO_USB_CLEAR and SIERRA_NO_REGISTER_40 flags.

2003-11-16  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c: Only do progress updates in sierra_get_string_register
	  if a command requires multiple packets.

2003-11-16  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c, sierra.c: Enable progress checks, since the recursion
	  cases have been removed from libgphoto2 and gtkam.

2003-11-15  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra.c: Make all ifdef's the same for recursion check and add
	  a missing ifdef.

2003-11-15  Patrick Mansfield <patmans@users.sourceforge.net>
	* olympus-desc.c, sierra-desc.h, sierra.c: Add basic camera
	  description for the oly 750uz (just the zoom support and
	  oly750uz_manual for now).

2003-11-03  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c: get rid of all progress updates to fix recursion
	  during capture per bug report 805858 from Harry Mangalam. The
	  fix sucks, since we now can't update gtkam (like scroll) while
	  operations are pending, but it fixes the bug.

	  This also gets rid of a bug where do_percent was no longer
	  getting initialized.

	  This really needs a change to gtkam or the gtkam <-> gphoto
	  interface, so we do not allow recursion but we do allow updates.

2003-11-03  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra.c: mark Epson PhotoPC 650 as SIERRA_NO_51, per bug 
	  report 831290 from Brian Lee.

2003-11-03  Patrick Mansfield <patmans@users.sourceforge.net>
	* nikon-desc.c: update a comment about the behaviour of cp 880 and
	  register 30.

2003-09-17  Marcus Meissner <marcus@jet.franken.de>
	
	* library.c: we were closing a context id we never opened. Not good.

2003-09-13  Patrick Mansfield <patmans@users.sourceforge.net>
	* epson-desc.c: remove unused commented out code.

2003-09-13  Patrick Mansfield <patmans@users.sourceforge.net>
	* epson-desc.c sierra.c: get rid of C++ style comments.

2003-08-30  Patrick Mansfield <patmans@users.sourceforge.net>
	* olympus-desc.c, sierra.c, sierra-desc.h: Add specific values
	  for the Olympus 3000z, based on input from Till Kamppeter
	  <till.kamppeter@gmx.net>.

2003-08-26  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c: Fix so on receipt of an unknown packet and a read of
	  zero bytes, we don't loop forever.

2003-06-14  Dan Fandrich <dan@coneharvesters.com>
	* epson-desc.c, nikon-desc.c, olympus-desc.c, sierra-desc.c, sierra.c:
	  include _stdint.h instead of stdint.h

2003-05-28  Patrick Mansfield <patmans@users.sourceforge.net>

	* epson-desc.c, nikon-desc.c, olympus-desc.c, and sierr.c
	  sierra-desc.c, sierra-desc.h, sierra.c: change u_int* to uint*_t,
	  and include stdint.h

2003-03-01  Patrick Mansfield <patmans@users.sourceforge.net>

	* sierra.c: Fix SIERRA_SKIP_INIT usage and add vendor/product
	  id's for Polaroid PDC 2300Z.

2003-02-27  Marcus Meissner <marcus@jet.franken.de>
	
	* library.c: We support EXIF download.

2003-02-15  Patrick Mansfield <patmans@users.sourceforge.net>

	* sierra.c, sierra.h: Add and use SIERRA_SKIP_INIT for use with 
	  Polaroid PDC 2300Z.

2003-02-15  Patrick Mansfield <patmans@users.sourceforge.net>

	* epson-desc.c, library.c, nikon-desc.c olympus-desc.c
	  sierra-desc.h, sierra.c, sierra.h: Remove use_extended_protocol
	  field and use a bit in the flags field instead.
	* sierra.c: cleanup some of the init code
	* sierra-desc.h: cleanup a comment

2003-02-02  Patrick Mansfield <patmans@users.sourceforge.net>

	* library.c: Add locking support just use the action
	  SIERRA_ACTION_PROT_STATE in sierra_set_locked.

2003-02-02  Patrick Mansfield <patmans@users.sourceforge.net>
	
	* library.c: Allow sierra_get_pic_info to always work even if
	  register 47 return no data - use other registers to get the data. 
	* sierra.c: Use register 43 to get audio, not sierra_get_pic_info,
	  so register 47 is not used prior to downloading.

2003-02-02  Patrick Mansfield <patmans@users.sourceforge.net>

	Idea based on a patch in a bug report from Valentin Rusu
	<sourceforge@valentinrusu.net>, this should also fix other cameras
	that do not return valid data for register 47.

	* library.c, library.h: added sierra_get_size
	* sierra.c: call sierra_get_size to get sizes via register 12 or
	  13, only call sierra_get_pic_info to get sizes for audio files.
	  Treat 0 length file size as unsupported.

2003-01-30  Lutz Mller <lutz@users.sourceforge.net>

	* sierra.h: SierraCamera is not needed any more.
	* sierra.c: Make some calls non-fatal.

2003-01-29  Lutz Mueller <lutz@users.sourceforge.net>

	* sierra.c: It seems the "Agfa ePhoto307" does not support the 
	  register 51. Reported by Ullrich Maenz <ullrich@familie-maenz.de>.

2003-01-14  Marcus Meissner <marcus@jet.franken.de>
	
	* *.c: enabled more translations, added some missing _().

2003-01-14  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c: Split the model string into manufacturer and model.

2003-01-03  Marcus Meissner <marcus@jet.franken.de>
	
	* sierra.c: Epson PhotoPC 650 at least partially working.

2003-01-03  Marcus Meissner <marcus@jet.franken.de>
	
	* library.c: Replaced stack allocated CameraList by dynamic 
	  allocated one, since this struct is huge.

2002-12-10  Marcus Meissner <meissner@suse.de>

	* sierra.c, sierra.h: replaced usb_wrap flag value by a generic
	  flags value.

	  Added a hack for "low speed" cameras and cameras which do not
	  like the register 51 being retrieved, like the Agfa ePhoto 780c
	  apparently.

2002-11-17  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra.c: start off with folder set to empty rather than "/",
	  since we have no idea of the camera directory on startup.

2002-11-17  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra.c: Change 2100UZ to be SIERRA_MODEL_CAM_DESC per
	  patch from C.A. Marby <marby@lhasa.harvard.edu>.

2002-11-17  Marcus Meissner <marcus@jet.franken.de>
	* sierra.c: Do not cast between time_t* and int*.

2002-11-10  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c: oops accidentally took out the retrieval of the
	  current picture number (it's used to set the file name if no
	  valid file name is retrieved), put it back.

2002-11-10  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c: Conditionally save the file path on capture.
	  Note that this requires gp_camera_capture() to allow a NULL
	  path, else the the sierra_capture is never called with a NULL
	  path.

2002-11-10  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c: Per patch and details from C.A. Marby
	  <marby@lhasa.harvard.edu>, fix bugs with capture: fix a bug I
	  introduced, put back the read after action of a SIERRA_PACKET_ENQ.
	  Move the timeout increase before the capture, and increase the
	  timeout to 20 seconds.

2002-11-05  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c: The 2100UZ seems to use oly3040_cam_desc (reported by
	  C.A. Marby <marby@lhasa.harvard.edu>)

2002-11-01  Patrick Mansfield <patmans@users.sourceforge.net>
	* PROTOCOL, epson-desc.c, library.c, nikon-desc.c
	* olympus-desc.c, sierra-desc.h, sierra.c, sierra.h: Add changes to
	  support the 0x6 get register strings, the extended protocol.
	  This gives roughly twice the download speed. This is not
	  supported for the default cases. Thanks to Selmeczi David
	  <david@esr.elte.hu> for discovering and coding up the original
	  patch for this support. Also includes a minor change in
	  library.c for the message when a recursive call is detected.

2002-10-27  Patrick Mansfield <patmans@users.sourceforge.net>
	* library.c: rename ifdef around recursive call problem, and 
	  change ifdef-ed out code to use gp_context_progress_start.

2002-10-20  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c (camera_init): Don't call sierra_init if the camera is
	  a 'Polaroid PDC 2300Z'. Reported by William Bader
	  <williambader@hotmail.com>.

2002-10-03  Lutz Müller <lutz@users.sourceforge.net>

	* Makefile.am: -I$(top_builddir)/libgphoto2

2002-09-21  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Don't tell the camera to switch to a speed it is 
	  currently operating at.

2002-09-21  Lutz Müller <lutz@users.sourceforge.net>

	* library.c
	* sierra.c: Make the check for the precence of a memory card
	  non-fatal.

2002-09-19  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_check_connection): Fix.

2002-09-07  Patrick Mansfield <patmans@users.sourceforge.net>
	* sierra.c
	* library.c: Avoid recursive calls from gtkam into get/set
	  functions by not calling gp_context_progress_update.

2002-08-11  Patrick Mansfield <patmans@users.sourceforge.net>

	* sierra-desc.c: set the widget info field.
	* sierra.c: Change GP_DEBUG's to be more consistent.
	* library.c: Do not call sierra_read_packet_wait after a
	  sierra_transmit_ack, since it's called by sierra_transmit_ack.
	  Add file name to progress bar in sierra_get_string_register.
	  Add recursion protection to sierra_get_string_register.
	  Increase the timeout temporarily for the next command after
	  capture completes.
	  Change GP_DEBUG's to be more consistent.

2002-07-09  Gilles Grandou <gilles@grandou.net>

	* epson-desc.c
	* sierra-desc.h
	* sierra.h
	* Makefile.am: add initial configuration support for epson
	  3000z through cam_desc. original code is still here for
	  other cameras which may rely on it (if any).

2002-07-09  Selmeczi David <david@esr.elte.hu>

	* olympus-desc.c: Patch aperature to use menu rather than radio.

2002-07-08  Patrick Mansfield <patmans@users.sourceforge.net>

	* nikon-desc.c: Add comment clarifying 995 non-support.
	* olympus-desc.c:
	* sierra-desc.h: Add sierra_default_cam_desc.

2002-07-06  Patrick Mansfield <patmans@users.sourceforge.net>

	* sierra.c: Output summary with warning if no memory card present.
	* library.c: Check for memory card before capture or listing.
	* sierra-desc.c: add extern round() rather than a complete hack.

2002-07-05  Lutz Müller <lutz@users.sourceforge.net>

	Patch by Thomas Reitelbach <tr@erdfunkstelle.de>:

	* sierra.c: Add support for Epson 850z.

2002-07-01  Patrick Mansfield <patmans@users.sourceforge.net>

	* nikon-desc.c
	* olympus-desc.c
	* sierra-desc.c
	* sierra-desc.h
	* sierra.c
	* sierra.h: Add the ability to put the camera manual text in the
	  camera descriptor. Added text for cp880 and cp995. Put text in
	  for the Oly 3040.


2002-07-01  Patrick Mansfield <patmans@users.sourceforge.net>

	Patch by Selmeczi David <david@esr.elte.hu>:

	* sierra.c: Use SIERRA_MODEL_CAM_DESC for some olympus models.

2002-06-28  Lutz Müller <lutz@users.sourceforge.net>

	Patch by Selmeczi David <david@esr.elte.hu>:

	* olympus-desc.c:
	* nikon-desc.c: Prepare for translation.
	* sierra.c: Use the new configuration dialog for more camera models.

2002-06-28  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.h:
	* library.[c,h]:
	* sierra-desc.[c,h]: Fix includes.
	* sierra.c: Remove cruft.

2002-06-28  Selmeczi David <david@esr.elte.hu>

	* olympus-desc.c: New.
	* Makefile.am: Add above file.
	* sierra-desc.h: Reference to olympus-desc.c
	* sierra.c: Use new configuration dialog for the 3040Z.

2002-06-27  Lutz Müller <lutz@users.sourceforge.net>

	* sierra-usbwrap.c: I missed one < GP_OK.

2002-06-27  Lutz Müller <lutz@users.sourceforge.net>

	Selmeczi David <david@esr.elte.hu> fixed the error checks. I added
	the CR macro and fixed the headers.

	* sierra-usbwrap.h: Fix header.
	* sierra-usbwrap.c: Check for gp_* < GP_OK instead of != GP_OK.

2002-06-26  Lutz Müller <lutz@users.sourceforge.net>

	Selmeczi David <david@esr.elte.hu> is working on supporting
	his camera. This is a first step to get his camera working:

	* sierra.c: "Olympus C-3040Z" is supported by this driver, too.

2002-05-29  Patrick Mansfield <patmans@users.sourceforge.net>

	* library.[hc], sierra.[hc], sierra-desc.[ch], nikon-desc.c: 
	  Add camera description table for camera configuration settings.
	  Add support for nikon coolpix 880 using the description table.

2002-05-26  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Handle the error where the camera sends strange bytes.

2002-05-26  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_check_connection, sierra_set_speed):
	  These functions are only applicable for serial connections.

2002-05-25  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: If we receive SIERRA_PACKET_SESSION_END, reestablish
	  the connection and switch to the default speed.
	  
2002-05-25  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c (camera_init): It seems the code I '#if 0'ed out is needed
	  by USB cameras...

2002-05-25  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c: '#if 0' some code that I don't think is needed at all.
	* library.c (sierra_init): Logs show that sierra_init does not
	  start a new session (i.e. no 0x53 instead of 0x43 needed).

2002-05-25  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_set_speed): A speed change automatically 
	  starts a new session.

2002-05-25  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: The first packet after initialization (sierra_init)
	  needs a special flag.

2002-05-25  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c (camera_init): Check if the computer supports high speeds
	  (i.e. 115200).

2002-05-25  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_check_connection): GP_ERROR_IO_READ is fine, too.

2002-05-24  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Imitate the behavior of the Windows driver and
	  check before each sierra_write_packet if the connection is
	  still open (sierra_check_connection), i.e. if the camera
	  has sent SIERRA_PACKET_SESSION_END.

2002-05-24  Lutz Müller <lutz@users.sourceforge.net>

	* library.c
	* sierra.c: Move the check if a speed change is really needed into
	  sierra_set_speed.

2002-05-23  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_init): Don't use sierra_read_packet_wait, 
	  use sierra_read_packet and resend the request on GP_ERROR_TIMEOUT.

2002-05-22  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_init): Portmon logs show that the port
	  is closed and reopened after SIERRA_PACKET_SESSION_END
	  has been received and before the initial handshake.

2002-05-22  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c: If the requested speed is 0, we set it to 115200.

2002-05-21  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c
	* library.[c,h] (sierra_set_speed): Introduce SierraSpeed - makes
	  reading the code easier. Set GP_PIN_DTR before initialization and
	  after speed changes. According to Portmon logs, sierra_init
	  must be called after a SIERRA_PACKET_SESSION_END has been received.
	  Implement that.

2002-05-21  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Yet another try to handle SIERRA_PACKET_SESSION_END.

2002-05-14  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Try to handle the strange 0x8c error.

2002-05-13  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Handle SIERRA_PACKET_SESSION_[END,ERROR] by reinitializing
	  the connection if this error occurs.

2002-04-27  Ilya Konstantinov <gphoto@future.shiny.co.il>

	* sierra.c (camera_start, camera_init): Send the
	  initialization sequence only on init. Olympus C-860L
	  stops communications when receiving an initialization
	  sequence after some communications have already occured.
	
	* library.h, library.c (sierra_ping -> sierra_init):
	  This function isn't really a "ping", since it can be used
	  only on startup.

2002-04-26  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c (camera_start): Forgot a gp_port_get_settings before
	  checking settings.serial.speed. Shouldn't affect anything though...

2002-04-17  Lutz Müller <lutz@users.sourceforge.net>

	Patch by Ilya Konstantinov <gphoto@future.shiny.co.il>:

	* library.c: break on timeout.

2002-03-29  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_ping): Retry up to 3 times.

2002-03-28  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Formatting.
	* sierra.c: Ping the camera before changing the speed.

2002-03-14  Patrick Mansfield <patman@aracnet.com>

	* sierra.c (camera_get_config_olympus, camera_set_config_olympus):
	  Fix getting/setting the shutter speed via conversion to int or
	  float.

2002-02-27  Lutz Müller <lutz@users.sourceforge.net>

	Patch by Patrick Mansfield <patman@aracnet.com>:

	* library.c: Stop the progress only if any has been started.

2002-02-22  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_get_string_register): Retry on timeout (after
	  sending nak).

2002-02-21  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c: Olympus C-860L has been reported to work with this driver,
	  too.

2002-02-19  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_list_files): No need to set the int register,
	  (sierra_get_string_register) will do that for us.

2002-02-18  Lutz Müller <lutz@users.sourceforge.net>

	Per Gilles Grandou's <gilles@grandou.net> request:

	* #undef HAVE_EXIF

	* library.c (sierra_read_packet): At least Nikon CoolPix 880 sets 
	  the checksum always to 0xffff (?!?).

2002-02-11  Lutz Müller <lutz@users.sourceforge.net>

	* Makefile.am: As long as there is EXIF code in here, add
	  EXIF_[CFLAGS,LIBS]. However, there shouldn't be any EXIF code here,
	  it should all be done by the CameraFilesystem...
	* library.c (sierra_list_files): Some cameras don't support filenames.
	  We are now that good in catching errors that we needed to adjust
	  the check here.
	* sierra.c: Remove wrong use of CHECK

	* sierra.c: added EXIF support.

	* library.c (sierra_read_packet): Improve debugging output by
	  reading several bytes at once. Should make transmission faster,
	  too.

2002-02-06  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.[c,h]: Lots of additional debugging output.

2002-02-06  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c (sierra_read_packet_wait): {int res=(res);... 
	  just cannot work. Read the macro definitions...

2002-02-05  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c (camera_init): Pass NULL as context, because we will
	  ignore those error messages and are just probing for the level of
	  support for filenames or folders.

	* library.c (sierra_read_packet): TYPE_COMMAND is a multi-byte
	  packet, too, according to protocol.htm (see photopc).

2002-02-05  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_list_files): For cameras that don't support
	  filenames, it is useless to try to get a filename for each 
	  file. Just try on the first one. If this fails, come up with 
	  dummy filenames for each file.

2002-02-05  Lutz Müller <lutz@users.sourceforge.net>

	* library.c (sierra_read_packet): Hopefully this fixes problems
	  with serial cameras: TYPE_DATA[_END] identifies packets of more
	  than one byte.

2002-01-29  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Cleanup.

2002-01-27  Lutz Müller <lutz@users.sourceforge.net>

	* sierra.c: %s/== GP_OK/>= 0. Fixes camera_config (for example).

	William Bader <william@nscs.fast.net> reported (partial) success
	with his Polaroid PDC2300Z.

	* sierra.c: New model.
	* library.c: Clean-up.

	* sierra.c: New model.

2002-01-19  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: I messed up the logic: TYPE_DATA and TYPE_DATA_END 
	  are _not_ single byte packets.

2002-01-17  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Improved debugging messages. I hope I didn't break
	  the logic...

2002-01-16  Lutz Müller <lutz@users.sourceforge.net>

	* library.c: Additional debugging messages.

2002-01-13  Lutz Müller <urc8@rz.uni-karlsruhe.de>

	* *.[c,h]: Remove references to gp_camera_set_error.

2002-01-09  Dan Fandrich <dan@coneharvesters.com>

	* sierra-usbwrap.c: Fixed a pointer arithmetic portability issue.

2001-12-01  Lutz Müller <urc8@rz.uni-karlsruhe.de>

	Suggestion from Stefan Höhne <s_hoehne@informatik.uni-kl.de>:

	* library.c: Check for filename == "        ". It seems his 
	  camera doesn't support filenames.
	* sierra.c: Add "Olympus C-2500L".
