[sane-devel] AGFA Spanscan E50 USB

[Bob Lockie]

I'm trying to get an AGFA Spanscan E50 USB scanner to work.
It didn't right out of the box so I have some learning to do.

What is the generic USB driver that is mentioned?
I configured USB scanner support into the kernel, it works as a module.
I am using the CVS version of SANE and the 20020926 snapscan backend 
(which version is in CVS SANE?).
Hopefully someone can interpret this for me.
The first cat is after I booted.
The scanner is recognized but there is no driver has claimed that 
interface (the usbscanner as mentioned in the docs at 
http://snapscan.sourceforge.net/).
usbscanner is supposed to be mentioned.

Why is there no manufacturer and product string for my webcam?


# modprobe  scanner vendor=0x06bd product=0x208f
# sane-find-scanner -v

checking /dev/usb/scanner0... open ok, vendor and product ids were identified

found USB scanner (vendor=0x06bd, product=0x208f) at /dev/usb/scanner0


Why do I have to provide the vendor and product to modprobe, I don't for my webcam?
