[sane-devel] Only superuser can scan

[Antony Gelberg]

Hi all,

This is a Debian testing box.  The normal user can't scan, but it's
different to permissions problems that I've seen before.  He can see a
scanner, but there is a question mark in the (incomplete) output of
sane-find-scanner.  It's a Canon lide 60 (genesys backend).  I have
bodged the permissions on /proc/bus/usb/001/002 to allow all rw, but no
difference.  It's running 2.6.15, with udev, not hotplug.

aft:/home/dr# sane-find-scanner -q
found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan],
chip=GL841) at libusb:001:002
aft:/home/dr# su dr
dr at aft:~$ sane-find-scanner -q

Any advice would be appreciated.
