Seems like whenever I make some progress, I hit another issue. I have more time to work on it this week, it's difficult to troubleshoot.
At the moment, it works for a bit, then stops sending/receiving for no reason at all. Seems to be mostly on larger data transfers. Sometimes even doesn't connect to the PC at all, I'm not sure if this is due to the constant plugging in/unplugging. The slowness is probobly because of the serial debugging, but it doesn't work at all when I disable this debugging. So my first thought its that something is going to fast, or I am not checking something I should be before sending data. Albert doesn't have much doc on how to create other USB classes. I did try his blogs but there is not enouf info. Maybe I'll shoot him an email. Matt.
