Ik heb even gezocht op internet. Op deze pagina:
http://home.scarlet.be/eddy_de_greef/Sane/index.html heb ik denk ik gevonden wat exact mijn probleem is:
Reported problems
*
The scanner is no longer recognized after a kernel upgrade to version 2.6.21+.
Around Linux kernel version 2.6.21, an incompatibility was introduced between the kernel and libieee1284 (the library that the mustek_pp driver uses to access the parallel port). The result of this is that the parallel ports are no longer recognized by libieee1284 and the scanner is not found. Typically, debug output (SANE_DEBUG_SANEI_PA4S2=128 scanimage -L) contains the following lines:
...
[sanei_pa4s2] pa4s2_open: `parport0` is not a valid device name
[sanei_pa4s2] pa4s2_open: returning SANE_STATUS_INVAL
[sanei_pa4s2] sanei_pa4s2_open: connection failed
Kijk maar naar deze uitvoer, vooral de laatste lijnen:

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).

Hoe kan ik dit nu oplossen?
