[sane-devel] Followup: Kernel claiming device?

Fri Jun 30 15:27:30 UTC 2006

I did some more reading and found other people had problems with this.
Especially in multi-function devices. Their solution was to comment out some
code in the backend or remove a usb module from the kernel.

I did an lsmod and found hpusbscsi was loaded whenever I plugged in my
Avision 220 scanner. I did a modeprob -r hpusbscsi and scanimage -L now
returns with my scanner.

But I still can't scan. When I do a scanimage, it waits for a long time and
then times out. I get some read errors: " Value too large for
defined data type" followed by some write errors.

Any ideas on the module load problem or the timeouts would be greatly
appreciated.

Thanks,
Kerry
