Those messages are not necessarily bad.  The "poll for hub" code sends
out requests looking for a device.  If nothing is connected it gets an
error.  I thought the messages only came out if "verbose" was
enabled...  (I need to check)

I don't know what the FADS h/w looks like - if their are no pullups on
the D+/D- lines and the it has the 15k pull *downs* on both lines you
can use the normal RXP/RNX insert detection code (i.e. you can turn
off the polling code).

Is there a device connected?

btw: I thought the 1khz timer signal needed to go to DREQ0, not DREQ1
