Hi, since USB 1.1 is available as supported protocol, why don't support USB 2.0 ?

USB 2.0 is 480 Mb/s. At a sample rate of 500 MS/s, the logic analyzer just isn't fast enough.

In general, you must sample at least 2x the signal rate to measure it.

I suppose if you could use have the logic only capture changes, and use a timer to time those changes, you may be able to do USB2.0, but I suspect that would require a re-architecture.
