I may be misunderstanding htings, but I don't believe that patch addresses the same issue I'm trying to fix (I've tested with it, and it doesn't cause any trouble for me, but it also doesn't seem to address the corner-cases I'm hitting). My "Improve gadget state disconnection handling" patch handles the fact that when we switch from B/gadget mode to A/Host mode, we don't always go through a gadget disconnect path. So instead of calling the dwc2_hsotg_disconnect() path initially when switching to gadget mode (to avoid the state complaining that we set it up twice), we should instead be calling dwc2_hsotg_disconnect() when we are setting up the A/host mode. So for example, the follow-on fix to the UDC state won't properly work without my "Improve gadget state disconnection handling" patch, and "cat /sys/class/udc/f72c0000.usb/state" will always return configured (assuming gadget mode was used once) regardless of the gadget state, since we don't actually call dwc2_hsotg_disconnect when the otg plug is removed. > Other 2 patches from series "[PATCH 0/3] dwc2 fixes for edge cases on > hikey" are Ok.
