I started thinking when I tried this git.ti.com 3.8 kernel, I might
have done 'devmem2 0x47401c60 b 0x81' to manually set the SESSION bit
after plugged a device. It was months ago, I don't quite remember what
I tested.

My build server is down this afternoon. Once it comes back next week,
I will try 3.8 again, to see how I can help on this USB1 host mode
issue. its devctl register should stay on 0x19 even nothing is
connected.
