Hey all,

First post - so bear with me.

I've been using Calibre for a while now (in Ubuntu), but recently it won't recognize when I plug in my reader (as Sony). The computer "sees" the reader, and I can get into the files on the reader, but I can't use Calibre to organize my ebooks.

I ran Device Detection Debug, and it says it can't find Calibre Mount_Helper, or something like that (The code is below).

Any thoughts? I'm really stuck, and not very strong in Linux...

regards,
Wargboyz
