[sane-devel] Plustek OpticSlim 2400 problem - solved

[Eggert Ehmke (FTV)]

Hi Stef,

I got it working! I got the original driver from the plustek homepage 
downloaded and unpacked-->bingo. Also in color mode it works perfekt.

Would it be helpful for other people to publish the unpack procedure? I did 
not find any really precise description, it was just try and error. I could 
provide a howto now. Is there a license issue about the original driver?

Thanks for your hints again!

Regards
Eggert
