Thank you for your thoughts. I could not get a logic analyzer to
figure out the signals on the lines. But, I could log the usb
interrupts from the device though.

Attached is the output when I have the old_scheme_first parameter set
to 1/Y. The device is recognized fine with a non-usb 3.0 port.
When I log from the device, I see just the Port reset. I do not see
the Set-Address request (or, any other txn coming through) coming
through to the device.
Thanks again for your thoughts. If you can think of something else to
check, please let me know.
Sorry for the bother,
Joe
