Not to introduce too much thread creep, but I've had similar problems getting Canola to recognize a flash drive, but I also can't get the default media player to index it (I can play tracks one at a time from it just fine, and examine it with the file manager, too). Has anyone had any luck with that (I'm also using Ogg files).

I ended up using YouAmp, which is nice, but still indexing a 32G drive to update its database.
