Plug a USB mouse or keyboard into one of the USB ports on the back or lower right side of your Desk Pro. Then, connect your laptop to the USB-C port on the Desk Pro. The computer will detect the mouse and/or keyboard and the device(s) will be available immediately.
If your computer supports Alt-mode Display Port, over the same cable you can use the Desk Pro as an external monitor, and work directly on it with your mouse and keyboard.
Your connected mouse and keyboard will appear to the computer as 'generic'. This means non-standard features (such as fingerprint activation) are not supported.
