Ah, yes best avoided !

Yes, it was short term desperation to try to point to a known device
but my USB numbers were changing here too, presumambly as I added
or removed other USB devices. I'll comment it out. But keep the [] :-)

Yes, Thanks ! I scanned a half centimetre wide strip which shows the error,
SANE_DEBUG_PLUSTEK=127 scanimage -x200 -y 5 > out.pnm 2> log
out.pnm is 10K, The log is 170K so for any on a slow net I copied it
& gzip'ed it to 10K, all here

I hope the log is useful to someone ?
I'm reading it with eyes of a newbie, but I see lot of
[plustek] usbDev_ScanEnd(), start=1, park=0
[plustek] We're little-endian! NatSemi LM983x is big!
[plustek] --> Must swap data!
line 127:
/usr/ports/graphics/sane-backends/work/sane-backends-1.0.25/backend/
plustek-usbhw.c: DBG( _DBG_READ, "--> Must swap data!\n" );
I dont know the code, if one could debug if swapping is happening OK ?
Is it concidence the white paper shows yellow then red exactly halfway
across the page.

BTW but probably irrelevant: scanner takes ages to start, I see the
default conf file has option warmup -1 = auto, I guess that's just
manufacturer being cautious.
Cheers,
