I have Plustek OpticPro PT12 scanner. It works reasonably well (1) in the
normal mode using Debian sarge, sane-1.0.7 (not modified) and
plustek-module-0_41_5 with 2.4.19 kernel.
But when I switch to transparency or negative mode both lights turn dark. Is
there any trick to switch ON this backlight. I have not changed any settings
in module options (
alias char-major-40 pt_drv
pre-install pt_drv modprobe -k parport
options pt_drv lampoff=180 warmup=15 port=0x378 lOffonEnd=1 mov=0 slowIO=0 \
forceMode=0
and also use all defaults in /etc/sane.d/plustek.conf
The results are the same with plustek-module-0_42 _9 and sane-1.0.9
I am using xsane and xscanimage when testing.
Best regards,

(1) when the scanner starts the system is very slow - pt_drv blocks most of
the CPU time.
(2) when I use 2.4.17 kernel EPP mode is detected OK by parport_pc, but with
2.4.19 I get only PCSPP in /proc/sys/dev/parport/parport0/modes
(Host bridge:[ALi] M1541, PCI bridge: [ALi] M1541, ISA bridge: [ALi] M1533
PCI to ISA Bridge [Aladdin IV])
(3) I have seen some OOPS messages with plustek-module-0_41_5 (when using
transparency/negative mode). Should I investigate it further and report?
