The USB packet decoder can decode full-speed and low-speed devices correctly, with 2.5v threshold set. But when a high-speed USB disk is plugged in, only threshold is set below 0.5v that I can see signals, and the decoder decodes a bunch of "SYNC ERROR".
Is DSView doesn't support high-speed decode or other problems? Sample rate is set to 500MHz.
