[sane-devel] Plustek 9636T memory test failure

[Oskar Schirmer]

Trying to get the plustek 9636T work
on an Ubuntu 10.04 500MHz x86 installation,
but it fails during detection. With
export SANE_DEBUG_PLUSTEK_PP=255 set,
scanimage run with root permissions says:

With comments dropped, /etc/sane.d/plustek_pp.conf is:

[direct]
device parport0
option warmup    -1
option lOffOnEnd -1
option lampOff   -1

Actually, the lamp, switched on with power up,
goes dark when scanimage is run, so some
parallel communication is probably working.

What's going wrong,
what does the memory test and IODELAY thing tell?

thanks,
