If I understand the man page correctly, ucycom is attached to uhidev,
so that much is correct.  For example, I have a ucom which attaches
to umodem, and the device identification is printed for the umodem, not
the ucom.  The question is why ucycom isn't picking up the device.  I'd
check the vendor and product ids against the table in ucycom.c.
