Hi,
Sorry I tried to post with the wrong e-mail.
So here it goes again.
I use debian testing with a 2.6.1 kernel.
Since "scanner" is obsolete now I tried to setup my scanner with libusb.
But after much struggling I haven't succeeded for now. I hope you can
give me some light :-)
sane-find-scanner works fine.
found USB scanner (vendor=0x06bd [AGFA], product=0x2061 [
Snapscan1212u_2]) at libusb:001:003
xsane launched as user won't work:

# Change to the fully qualified filename of your firmware file, if

firmware /etc/sane.d/SnapScan1212U_2.bin
# If not automatically found you may manually specify a device name.
# For USB scanners also specify bus=usb, e.g.
/dev/usb/scanner0 bus=usb
# /dev/usbscanner bus=usb
# I have commented all the scanners and left only mine:
# Agfa 1212U
#usb 0x06bd 0x0001
usb 0x06bd 0x2061
/dev/usbscanner is a symlink to /dev/usb/scanner0 which is my scanner...
I have tried with commenting out "/dev/usb/scanner0 bus=usb" in
snapscan.conf. I have also tried /dev/usbscanner.
