Calibre doesn't detect reader
I tried to transfer some books to my Sony 505 today, but my device doesn't show up. I was running v 0.5.1, but the last time I used calibre w/ my reader was before the v 0.5 release. I installed v 0.5.2, but still have the same issue. My computer "sees" the reader and I can access files through "windows explorer". I'm running 32 bit Vista Home Premium. Anyone have any suggestions?
