Thanks for the hints. This problem is because reason dwc3_gadget_run_stop() is timing out during the suspend sequence and so dwc3_disconnect_gadget() and __dwc3_gadget_stop() are not being called. dwc3_suspend() does not consider dwc3_gadget_suspend()'s return value and happily continues suspending the machine. If I force dwc3_gadget_run_stop() to return 0 then everything works fine. Any ideas why DWC3_DSTS_DEVCTRLHLT is not getting set? I checked that DWC3_GEVNTCOUNT(0) is zero. cheers, -roger -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
