[sane-devel] Avision scanner timeout

[Kerry Menzel]

Hi,

I am trying to get an Avision AV220 scanner to work with Redhat Linux 9
(2.4.29-abi). When I connect the scanner the hpusbsci module is
automatically loaded. Sane-find-scanner finds the scanner ok. Scanimage -L
does not find it. It reports that the kernel has the scanner. So I do a
modprobe -r hpusbsci and remove the module. Then scanimage -L times out. I
get the following debug. Anybody know what is causing this? Should I unload
the module or is there another way to connect using that module.

Thanks for the help.
