["Egor Tur" <worldeb@inet.ua>]

Hi folk.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

What must I do for using scanner?
I try to change owner/permission  for /proc/bus/usb/"BBB"/"DDD" but this not
work.
I also adde users to scanner group.
I try using scanner as root and user - not work. Scanner is not detected.

Other question: what can I do that my system does some signal (beep or
message) about
new USB device? And how can I (or another user) mount/umount USB disks without
root
permissions. Hotplug does this?

Thanx.
