Which of the tests are you talking about? Which particular USB CV are
you running?

I don't remember ever seeing this with dwc3. How should I go about
triggering this problem? If this was really the case, then we would have
this on *all* UDCs.

I just did a fresh install of USB 3 Gen X CV (that I just download from
usb.org). Ran Chapter 9 tests against a HS dwc3 board I have around and
I can't see the problem you're talking about.

Here are all my non-endpoint interrupt events in order. Test passes
fine. If disconnect, reconnect and run the tests again, then Reset will
be driven on the bus which will cause address to be reset.

Can you share more details about the problem you're facing?
