Hi!

I've got a "Plustek OpticPro 4800P". Whenever I am scanning something, the
CPU load goes to maximum and doing anything else while scanning (such as
reading my mails with mutt) results in a corrupted image.
I can imagine that this happens on low-end systems but I don't consider my
Athlon-700 a low-end system. :-)

the relevant lines from my /etc/modules.conf are:
   ### parport
   alias parport_lowlevel parport_pc
   options parport_pc io=0x378 irq=7 dma=none

   ### scanner
   alias char-major-40 pt_drv
   pre-install pt_drv modprobe parport
   options pt_drv lampoff=180 warmup=30 port=0x378 lOffonEnd=1 mov=2

and dmesg says:
   pt_drv : driver version 0.37-24
   parport0: PC-style at 0x378, irq 7 [PCSPP,TRISTATE,EPP]
   parport0: cpp_daisy: aa5500ff(38)
   parport0: assign_addrs: aa5500ff(38)
   parport0: cpp_daisy: aa5500ff(38)
   parport0: assign_addrs: aa5500ff(38)
   pt_drv0: Primax 4800 Direct found on port 0x0378
   pt_drv0: Lamp-Timer set to 180 seconds.
   pt_drv0: WarmUp period set to 30 seconds.
   pt_drv0: Lamp switch-off on driver unload.


So, what am I doing wrong?

Greetings
Gert
