OK, done. It works now as root with port /dev/parport0, but still as normal
user, I get the following:
sven@gimli:/dev$ /usr/src/sane-backends-1.0.12/tools/umax_pp -p -t 32
[sanei_debug] Setting debug level of umax_pp_low to 32.
[umax_pp_low] SANE_INB level 3
[umax_pp_low] sanei_ioperm() could not gain access to 0x378
failed to gain direct acces to port 0x378!
sven@gimli:/dev$ ls -l parp*
crw-rw-rw- 1 root lp 99, 0 2003-10-13 12:18 parport0
crw-rw-rw- 1 root lp 99, 1 2003-10-13 12:18 parport1
crw-rw-rw- 1 root lp 99, 2 2003-10-13 12:18 parport2
PPDIAG (as root) is still:
sven@gimli:/dev$ sudo /home/sven/bin/ppdiag
S01: parport built as module
S02: ADDR :0x378
S02: IRQ :7
S02: DMA :no DMA used
S03: no parport parameters
S10: couldn't find if ppdev is built in or a module
S10: It is likely that your kernel configuration has no ppdev support
S10: exiting ...
Did I miss anything?
