ohci.c uhci.c usb.c usbdi.h
Log:
Use a different task queue for host controller and peripheral driver
tasks. Since the host controllers rely on tasks to process transfer
timeouts, if a synchronous transfer from a driver was invoked from
a task and timed out, it would never complete because the single
task thread was stuck performing the synchronous transfer so couldn't
process the timeout.
This affected the axe, udav and ural drivers.
