No - the scanner is supported.

What do you mean by "locks-up" - does the scan bar return to the 
home position or not?
If you only call scanimage without any further options, then the
scanarea is pretty small.

As the scan-head moves, there's no need to tweak anything.

This is completely wrong - the LiDE30 is supported by the plustek backend
and not by the canon backend - so you need to look at the plustek.conf
file - somewhat confusing I know ;)
