[sane-devel] snapscan e40 (usb) problem

Try to set SANE_DEBUG_SNAPSCAN=255 before and mail me the output.

> # ls -l /dev/ | grep scanner
> crw-------    1 root     scanner  180,  48 May 21  2001 usbscanner

This is fine, but will restrict scanner access to root (do "chmod g+rw 
/dev/usbscanner" to allow access for members of the scanner group).

You should delete the entry "usb 0x06bd 0x208d". The snapscan backend 
currently doesn't implement this sort of auto-recognition (but it's planned 
for the future). You don't need to recompile.
