Hello List!

I just unpacked my brand new "CanoScan LiDE 25", which isn't listed on
the supported devices list (probably because it's released a month ago).

Well, here is what I found out:

It seems to use the same chipset as LiDE 20 (LM9832/3). So it might be
supported by the plustek-backed. What might I do to test it further?

scanimage -L said no scanners were identified....
