[sane-standard] problem with umax_pp

[Nicolas FRANCOIS (AKA El Bofo)]

I've got a HP3200C on parport (AMD 2600+ on ASUS KT333 MB, Kernel 2.4,
sane-backend 1.0.14). After successfully installing the backend, I have
some problems with parport detection. Sometimes it partially works,
sometimes I'm told I haven't got a parport !

An example :

root:/usr/src/sane-backends-1.0.14/tools# ./umax_pp -p -t 1 -n
/dev/parport0
[sanei_debug] Setting debug level of umax_pp_low to 1.

This is what ppdiag tells me :

root:/usr/src/sane-backends-1.0.14/tools# ppdiag 
S01: parport built as module
 
S02: parport0:
S02:    modes:PCSPP,TRISTATE,EPP
S02:    ADDR :0x378
S02:    IRQ  :no IRQ used
S02:    DMA  :no DMA used
 
S03: no parport parameters
 
S10: ppdev built as module
 
S12: /dev/parport0 exists ...
S12: /dev/parport0 is readable ...
S12: /dev/parport0 is writable ...
 
successfull end ....

Funny, isn't it ? I'm completly stucked, so could you help a little, or
give me some pointer for more documentation ?
