I had similar problems with my Agfa Snapscan 1236U. I am able to get a
preview and the final scan, but my usb system hangs (errors like the one
above) after the next "action". So I have to restart my scanner after
each scanned picture.

But ... we got a digicam these days and I faced similar problems: If I
start gtkam a second time, it cannot find the camera ... guess what
errors appear in the log ...

As long as the camera and gtkam work with my notebook without problems,
I guess this is not an error of sane but of the usb system (libusb,
chipset on my desktop pc, what ever ..).


If one has a solution, I am interested, too ...


FYI
