In lines 477-481 of firmware/usbstack/usb_core.c (noticed in r16521) there is a possible bug. I'd make a patch but I don't know the correct fix.

The relevant text is:
if (req->wValue)
usb_drv_stall(req->wIndex & 0xf, false,(req->wIndex & 0x80) !=0);
usb_drv_stall(req->wIndex & 0xf, false,(req->wIndex & 0x80) !=0);

This is basically if(something) do_x(); else do_x(); do_y();
Very confusing at best.

I mentioned this in irc, but nobody seemed to notice. Sorry if someone is already looking into it.
This task depends upon

Fixed. I saw it in the irc logs.
