FWIW: For the fotg210 OTG controller (*) I have a (almost) full understanding which parts are changed from the Farday IP. For obvious speed reason they done the "usb gadget" work in the boodloader. I can achieve about 30Mib/s in device mode, which is impressive ! For tests it should be possible to (re)use the vbus pin as id pin, so I can trigger the "internal" id pin in the syscon registers. The otg controller driver need a complete rework, already started. (*) As with my first approach the HCD driver is upstream, so also the the gadget driver. Adding the otg driver without breaking existing hardware is a challenging/fun/whatever work.
