Martin Whitaker 3a107018e5 Reset EHCI controller after port scan if no keyboards are found.
Low and full speed USB devices that are attached directly to an EHCI port
have to be handled by a companion controller (either UHCI or OHCI). We hand
over ports when we detect a low or full speed device is attached by setting
the Port Owner bit in the Port Status and Control register. However some AMD
companion controllers fail to detect the device after this has been done.
Resetting the EHCI controller works around this quirk.

This fixes issue #6 and issue #71.
