Signal quality problems are still an option ... I've seen the FX2
protoboard work OK with VIA-based adapters.  I recall hearing that
getting devices to enumerate at both full and high speeds wasn't
always straightforward.

So far so good -- the "chirp" did its bit.

[ repeats ]

Token value translates as an 8 byte SETUP packet that halted because
of three consecutive transaction errors ... like CRC error, timeout,
or bad PID (like a NAK or NYET response).  Bad signaling could cause
CRC and timeout errors, I think.
