USB Connectors
There are two Universal Serial Bus (USB) connectors located on the rear
panel of the computer. These USB connectors support only the HP
keyboard, scroll mouse and hub. You can connect the HP keyboard, scroll
mouse and hub in either of the USB connectors.
The mouse and keyboard were shipped with your system unit, and the
HP hub can be ordered separately. Note that you should consult the
documentation that accompanies each input device for specific
information concerning its use.
