commita8d3e4a734upstream. On Rasperry Pis without onboard USB hub the power cycle during power connect init only disable the port but never enabled it again: usb usb1-port1: attempt power cycle The port relevant part in dwc2_hcd_hub_control() is skipped in case port_connect_status = 0 under the assumption the core is or will be soon in device mode. But this assumption is wrong, because after ClearPortFeature USB_PORT_FEAT_POWER the port_connect_status will also be 0 and SetPortFeature (incl. USB_PORT_FEAT_POWER) will be a no-op. Fix the behavior of dwc2_hcd_hub_control() by replacing the port_connect_status check with dwc2_is_device_mode().
