There's a couple more patches to deal with some issues with disconnecting a USB device (or safely removing a USB mass storage device) when the bus is suspended. See the patches starting in this thread: http://marc.info/?l=linux-usb&m=129421308020494&w=2 Try applying the first five patches and let me know if you still see any issues. The fourth patch has a known compile warning (it will get fixed shortly) but you shouldn't run into that particular error path.
