Nope, the scanner is the only device. I've tried both ports on the back
of this machine.

Ok, I can try another computer, I guess. I tried Knoppix CD just now and
I got the same I/O errors. I'd rather buy a new scanner than install
Windows on my desktop machine ;) I have used this scanner on Windows in
the past, without problem -- but just not on this machine. It's a MSI
K7T266 Pro2 motherboard. Maybe I could throw in a new hard disk and
It would be too bad if it's a motherboard. Seems unlikely, though.
If I were able to test the the hardware and find out it's ok, then where
should I focus my debugging?
Is the usb_control/bulk_msg: timeout message generated in the scanner
module? And is that what is causing the front-end X apps to report the
"I/O" error? I wonder if I could get the scanner module to tell more
about what's timing out.
I assume the scanner module talks to the usb module to get out to the
It seems odd to me that one X frontend works yet the other fails with an
I/O error. I don't know the Sane API but I assumed that the all apps
would see the same problem using the same API.
A lot of work to just scan a few images of the kids!
Thanks for your time. I'll post again if I can figure anything out.
