Summary: Error reading from Olympus C-2100 Ultra Zoom

Initial Comment:
 
I have problems reading images from an Olympus 
C-2100 Ultra Zoom camera. The camera has worked fine 
with gphoto2 for over a year, no problems at all. Now it 
suddenly doesn't work at all anymore, reading from the 
camera gives an error, see the link: 
 
http://www.infa.abo.fi/~chakie/media/gphoto2.txt 
 
The camera is detected by the USB subsystem just 
fine, but each access gives this error in syslog: 
 
usb 2-3: new full speed USB device using ohci_hcd and 
address 7 
usb.agent[7202]:      libgphoto2: loaded successfully 
usb.agent[7202]:      usbcam: loaded successfully 
usb 2-3: usbfs: interface 0 claimed while 'gphoto2' sets 
config #1 
usb 2-3: gphoto2 timed out on ep0out 
 
The last line is new, the timeout hasn't been there in 
the past. gphoto2 finds the camera ok: 
 
% LANG=C gphoto2 --list-ports 
Devices found: 1 
Path                             Description 
-------------------------------------------------------------- 
usb:                             Universal Serial Bus 
 
However, getting info about the camera fails, with a 
similar timeout and error as in the link above: 
 
% LANG=C gphoto2 --summary 
Segmentation fault 
 
This is a Debian unstable system, the system is up to 
date and packages related to gphoto may have 
changed. No custom packages are installed, just the 
stock ones. 
 
Packages and versions: 
 
libusb-0.1-4,      1:0.1.10-2 
gphoto2,            2.1.5-1 
libgphoto2-2,      2.1.5-3 
libgphoto2-port0, 2.1.5-3 
hotplug,             0.0.20040329-16 
 
Note that gphoto2 has worked fine for over a year, and 
I have done no manual changes to the USB, hotplug o 
gphoto subsystems.

Same error, same segmentation fault.

The kernel in the above tests has been Debians version of 
2.6.9 and 2.6.10. Older versions have worked fine, as did 
2.6.9 a week or two ago.
