[PATCH] USB Storage: port reset on transport error
This patch causes a port reset whenever there's a transport error or abort.
If that fails it reverts back to doing a mass-storage device reset. It
started life as as497 and was rediffed by me.
This makes error recovery a lot quicker and more reliable.
