Daniel Verkamp 0dcbfa1176 usb: avoid setting configuration when unnecessary ... On devices with only one configuration, skip the code that attempts to change the device's active configuration, since it must always be the single available configuration. This works around an issue observed with some USB devices (e.g. Servo Micro) where the initial Get Configuration control request fails with -EPIPE.
