Greg pointed out to me that he’s turned over ownership of
drivers/usb/serial/pl2303.c … so I thought I’d contact the list instead.

I found my udc in v4.6. I played around with the kernel config for a
while and found the option that enables it. I think I changed dwc3 from
'dual role' (otg I guess) to 'peripherial' and got it's UDC and got a
few gadgets going.

hmm, maybe this should be moved to Documentation/driver-
Instead of *always* dumping raw ctrl bytes, let's decode standard
requests which will make the lives of those debugging DWC3 quite a bit
easier.
Output will now look like so:
irq/34-dwc3-1594 [000] d..1 107.573081: dwc3_ctrl_req: Get Device
Descriptor(Index = 0, Length = 18)
irq/34-dwc3-1594
Document a few details about DWC3 in order to help people report bugs
and debug DWC3.

Instead, we can require caller to pass a buffer for the function to
