xsane and canon LiDE 30

[Seth Hasani]

Hey, I've just started using a canon LiDE 30 with Ubuntu. I plug it in and
Ubuntu recognizes it instantly and it uses the plustek drivers.  Beautiful
work devs. However when I attempt to scan at a resolution higher than 75x75
the scan comes out with all sorts of wavy lines. Anybody out there using
this same scanner and having it work properly? How do you have it
configured.

Another thing is in gimp when I go to the file -> acquire -> xsane menu, it
lists my tv card as a default source and has to rescan to find the scanner.
I wont usually unplug the scanner so it will always be connected, how can I
make it so that this is the default all the time?
