Hi Dave

We're currently working on USB Device Controller implementation. We
already have a working setup in our lab which these changes were verified
on. We passed USBCV 3.0 and 2.0 tests with this setup.
In parallel we added SuperSpeed support to the dummy_hcd module and tested
the patch using it as well. Changes to dummy_hcd will be release in a few
days.

Regards,
Tanya
