The Si4713 development board contains a Si4713 FM transmitter chip and is handled by the radio-usb-si4713 driver. The board reports itself as (10c4:8244) Cygnal Integrated Products, Inc. and misidentifies itself as a HID device in its USB interface descriptor. This patch ignores this device as an HID device and hence loads the custom driver.
