Have you already tested this? I never tried changing mode via sysfs, but

only calls ops->set_mode() but nothing else. To really switch the mode,
the driver has to talk to the root hub, and manipulate the SESSION


I haven't actually tried this. I need to hack together a USB cable to test it in host mode (Mini-B to Mini-B w/ powered hub).
