I knew, I was asking for a problem:-)

I've got a camera Concord EyeQ 4330z, which is partly supported by
gphoto2. I knew that, and, sort of, learned to live with that - just don't
try to list files on the camera. Downloading and deleting works fine, but
listing works only ones. After that all further operations fail with a
bubble error. I already posted questions to this respect here and on
gphoto mailing-list. Looks like, this is not going to be fixed, because of
the usual closed specs... That's how it was under 2.4.

Today I tried it under 2.6. Downloading and deleting works as before.
Listing hangs immediately - already on the first attempt - and stays in
uninterruptible state. After that USB becomes unusable, and unremovable.
Eventually, I couldn't even reboot the PC properly. I captured backtraces
with the same camera. If it is of some use, I can upload the shots on the
web.

The question is - can the error-recovery be improved in such situations?
It's a UHCI host.

Thanks
Guennadi
