Summary: Failure to download file from Canon EOS-350D

Initial Comment:
Sometimes it happens that my camera contains a file
that resists downloading with gphoto (using command
line utility). Error is:

49.546187 gphoto2-port(2): Reading 512=0x200 bytes from
port...
49.546997 gphoto2-port(2): Could only read 0 out of 512
byte(s)
49.547009 gphoto2-port(3): Empty hexdump of empty buffer
49.547018 gphoto2-port(2): Reading 512=0x200 bytes from
port...
57.548259 PTP2/library.c(2): PTP: gp_port_* function
returned 0xffffffde         -34
57.548294 context(0): PTP I/O error

*** Error ***              
PTP I/O error
57.548321 libgphoto2/gphoto2-filesys.c(2): Download of
'IMG_0289.JPG' from '/store_00000001/DCIM/202CANON'
(type 1) failed. Reason: 'Unspecified error'
57.548331 gphoto2-camera(2): Operation failed!
*** Error (-1: 'Unspecified error') ***       

Output of

env LANG=C gphoto2 --debug --get-file "220"

is available at http://raven.oook.cz/gphoto-typescript.gz

It happens randomly, usually it's single file on 2GB
card. The file is retrievable with standard PTP driver
in Windows XP.

Figured out this is a bug in FreeBSD EHCI driver. You can
probably close this Bug.

I managed to reproduce the bug on another file, with 2.1.6
and 2.1.99. Filesize this time is 1889780 bytes.

Debug logs:
http://raven.oook.cz/gphoto/debug.2.1.6.gz
http://raven.oook.cz/gphoto/debug.2.1.99.gz

I can get you the JPG file too, if you need it.

I can't, sorry. I don't have saved record of other failing
files, and I don't have a failing file on any flashcard at
the moment.

it seems to download the file fine , the last 2 bytes are 
FF D9. 
 
can you check other filesizes?

The filesize reported in the typescript is valid:

PTP2/library.c(2): ObjectInfo for 'IMG_0289.JPG':
PTP2/library.c(2):   ObjectCompressedSize: 2272244

sorry for getting back so late. 
 
hmm. the transfer log looks fine. :( 
 
can you determine the filesizes that are problematic? I 
think it is dependend on the filesize.
