[sane-devel] Re: (Mis)Configuring 0x04b8:0x010c

[Adam Bogacki]

Using modconf I installed 'uhci-hcd' but could not find 'usbfs'.

I've mounted both on /etc/fstab

and now I find

and sane-find-scanner can now FIND it ...

but 'scanimage -L' does not ...

... nor does xsane. ["No devices available"] nor GIMP 
(File->Acquire->Xsane),

and iscan tells me

"Could not send command to scanner."
"Check the scanner's status."

The missing ingredient may be 'usbfs' which should be part of the kernel.

The scanner is plugged in and powered on.

What am I missing here ?
