The usb8x keyboard driver is compatible with any keyboard conforming to the USB HID keyboard standard. However, it is not compatible with devices that have a keyboard connected to an internal hub (combination keyboard/mice, for example).
The keyboard driver is initialized via KBDInit. This entry point initializes both the driver and the keyboard hardware, so you may want to check to see if a device is connected via IsDeviceConnected first.
After initializing the keyboard, use KBDGetKey to get keypress information. The driver maintains a 6-key keyboard buffer, so be sure to check for new keypresses with KBDGetKey regularly so the buffer doesn't fill.
