Okay. I'm stupid. I wasn't doing it as root.

When I am root and I do "SANE_DEBUG_PLUSTEK_PP=255 scanimage -L" I get this:

So - that is good right?

Now, how do I access the scanner not as root? When I run Xsane as me, it 
says no devices found.

If I do gksudo xsane, I get something, but also a warning for running as 
root.

I followed this how to: 
http://www.linuxprinting.org/download/digitalimage/Scanning-as-Normal-User-on-Wierd-Scanner-Mini-HOWTO.txt

but it is still saying 'no devices found' unless I run it as root.

Could you point me in the direction I should go next?

Thanks!
