The USB-231-OEM is a USB 2.0 high speed device that is compatible with USB 3.0 ports. The device is also
compatible with USB 1.1 ports, but use with this older hardware is not recommended due to longer initialization
times that can occur when the USB-231-OEM is connected through USB 1.1 ports or hubs.
