OHCI WITH EHCI
2013-9-11: OHCI does not work with EHCI. At present, EHCI receives the
full- or low-speed devices and correctly hands them off to OHCI. But, for
some unknown reason, the connection is lost and the port reverts to EHCI which
returns the port to OHCI. This sequence of connection events occurs
indefinitiely. OHCI does work without EHCI enabled, however.
2013-9-19: OHCI works correctly with EHCI. EHCI will handle high-speed
device connections; full- and low-speed device connections will be
handed-off to the OHCI HCD.

to test interrupt endpoints.

2013-8-26:
The hand-off of full speed devices to OHCI does not work. In this
case, OHCI gets the port, but the port is reset, lost by OHCI and
returned to EHCI. EHCI sees the full-speed port and hands it off to
OHCI and this sequence continues forever.
