Thanks Patrick (and apologies for the previous wrong name), the reason I
ask is I'm testing an rk3288 with the DM_USB_GADGET support enabled for
it's dwc2 OTG controller. The controller still works without
DM_USB_GADGET enabled, but it fails to enumerate any USB devices when it
is enabled. Is there anything specific required apart from enabling
DM_USB_GADGET?

=> usb start
starting USB...
scan end
No controllers found
