I do have a USB to parallel port converter, which works fine with my printer, but I can't get it to recognise my scanner. sane-find-scanner -p -vv /dev/usb/lp0 doesn't find any scanners. Is there something else I should try, or won't it work with a converter? No answer to this so far. Should I just give up? I'm no scanner/sane specialist, but do remember a printer will even work with a unidirectional parallel port, data just going computer to printer, whereas a scanner feeds a lot of data back, (PC BIOSes have various EPP/ECP etc modes, some modes support nibble mode too, ie 4 bits each way for a PL-IP connection etc), So maybe your USB to parallel device may need to support bidirectional (if it can), may need to be told to configure itself in bidirectional mode etc. How you might set about doing that I cound't advise, but would depend on your device manufacturer which Unix you are using, whatever it's USB control vagaries might be.

[sane-devel] Formulardaten
As robots attack the sane web page form that dumps on list, seen Message-id: tincas-30763098/-20070831T050235-xbhgzFMV at infong100.kundenserver.de I suggest whoever maintains that form page, should add a trick similar to (but please not the same as) I use on my ski booking web form here http://www.berklix.org/ski/form.html That will prevent attack robots, leave it only open to human abuse. -- Julian Stacey.

Maybe sudo doesnt check if your UID is in group 0 in /etc/group. whereas su does check bounce you. -- Julian Stacey.
