[wellylug] Canon Scanner on Slackware 10.1, invalid group problem

[Pete Black]

Benjamin,

That scanner is specifically unsupported - Canon refuse to release specs 
or drivers, it doesnt seem to be based on the same platform as other 
Canon scanners and even Mac support is stuck at OS9 (No OSX driver for 
this model) - I know because a have one as well.

-Pete
