Vincent, thanks for posting about the Thesycon USB Descriptor Dumper. I just check my new Steinberg UR824 last night and it uses asynchronous syncronization. I thought it did, but wanted to confirm. The UR824 uses the same clocking method (DICE 2 digital input chip with JET Jitter Elimination by TC Electronic) as the new Mytek 192 stereo which is also asynchronous.
