I discovered (not with any help from the lack of documentation from C-media) that the 'HOOK' signal is
actually available to be read (but not written). Therefore, the "GPIO2" signal can at least now be used
as an input.

The code revision (chan_usbradio.c) to support this should be available via SVN at abut 12:15 PDT today (when the public
SVN server updates).

Well, it's better then nothing......
