Hello-
Trying to run CDP mode (all jumpers off, S1 set to CDP) I'm having trouble getting the module to respond- wondering if I have a bad board? I never get a pulse back on D- when the device drives D+.

Powered from the upstream host- a PC in the trace I posted, but we've also tried from our embedded device which has the requisite 1.5A supply (but no handshake chip yet). It was reported to me that in early debug an external supply was tried as well, but I don't have scope traces from that attempt.
Charging device is a Samsung Galaxy Tab A6.
Hi Adam-
Well, for whatever reason (probably user error ;-) the eval is behaving itself now- the traces are as expected.
Sorry for bugging you!
