This is what developers said: "Note that the backend needs to run as root. To
allow user access to the scanner run the backend through the network
interface (See saned(1) and sane-net(5)). A more relaxed solution (security
wise) is to add suid bit to the fron� tend (See chmod(1)). The backend drop
root priviledges as soon as it can, right after gaining direct access to
IO ports."
Also, Stef Voltz tell me:
"Try usin gthe ppdev mode. With latest version, you may launch xsane as:
xsane umax_pp:/dev/parport0 , and then run as normal user. Provided
that
ppdev device is usable by user, and exists in MDK 8.2 (which should be the
case).
Also, you may edit umax_pp.conf in /usr/local/etc/sane.d to have a
'port'
option which points to /dev/parport0. Here's an excerpt from my umax_pp.conf:
....
# DEVICES #
# specify the port your scanner is connected to. Possible are 0x378 (lp0)
# 0x278 (lp1)
#port 0x378
port /dev/parport0
# the following options are local to this scanner"

Suerte.
