Human Interface Device (HID). You may need to install
HID drivers and enable USB support. You can install
these drivers from the operating system CD before you
connect the SMART USB adapter. However, when you
connect the adapter, the Windows operating system
prompts you to install the USB HID driver if it’s not
already on your system. For more information, read the
documentation that came with your operating system.
