It's working fine here on my Acer Prisa 620. Since lineart is not very=20
thoroughly tested (few people seem to use it) it's possible that it=20
never worked on the 3300u.

Unfortunately I don't have access to an 3300u. Could you send me a=20
debug log of a lineart scan?

To produce it, run=20
SANE_DEBUG_SNAPSCAN=3D255 xscanimage 2>debug.log
select a small scan area and a low resolution and scan an image. Exit=20
xscanimage and send me the debug.log file. It would also be helpful=20
if you could include the image file, once as lineart, once as=20
grayscale.

It may also be neccessary to get an USB trace of a windows scanning=20
session, but maybe the debug log is sufficient.
