USB Interface
The reader attaches directly to a USB host, or a powered USB hub, 
and is powered by it. No additional power supply is required. 
When using a USB interface, the reader auto-detects the USB ca-
ble and defaults to either the USB keyboard interface (GD4330) 
or USB-OEM interface (GD4310).
