device mode

[cleverca22]

had a quick glance over the readme and other issues, and dont see a clear answer

does this driver support both host and device modes? or only host mode?

i'm interested in using it to emulate a usb device on an rpi4, where the dwc controller is routed to the USB-C port

I believe it's host only. I don't know USB well enough but I believe at most you might be able to do OTG with rpi.

i now have a partially working gadget driver
it can respond to control-in transfers, but it cant initialize the controller or enumate properly
it relies on the firmware leaving things initialized and already enumated to function, but its still a decent starting point
