G41G Telematics Gateway, USB port supports in device mode only.
Changing the USB role through software is not possible as the hardware does not support it. If required, minor change will be needed to support the USB port as OTG , which we could do for volume production.
Kindly connect with iWave representative to discuss the technical requiements and support for the hardware change.
