Bug Description

I've been seeing USB issues on my beagle xm board with the latest linaro-2.6.38 tree, where when the system boots, lsusb will only show the root hubs, but no devices.

Andy reported seeing similar on his overo board, so I bisected the issue
down to:

    variant board files.

I've also verified the same issue is present in 2.6.39-rc1

Yes, the reset polarity patch [1] fixes this bug on my Beagleboard xM. USB peripherals are recognised and the on-board ethernet now works. (I note that the name for the on-board ethernet is now eth0 whereas in 2.6.38.1 it was called usb0)

The patched worked against my Overo as well. Keyboard and mouse are functional.
