Hi Scott,
I know, I've independently started work on bringing our board over to the latest analog devices release kernel. That's what I'm working on. However, I find that on the BF526 I get the same issue as Rob, being that our board cannot recognize USB devices. Our previous kernel, based on 3.0.8 does work on the same hardware.
Hence my question whether or not your comment regarding kernel 3.7 and USB host mode still holds for the BF526/BF527.
