In our case, we have been using the "usb -f" command but it still only
finds HID type devices on the first probe after reset. On later
"usb -f" it only finds the hub. We are using the external Phy module
which is likely the problem. We have verified the clocks are at 60
mhz. We plan to readdress this issue in a couple of weeks when our
final hardware arrives.
