You can attach a USB hub device to the USB connector. The USB hub device can support multiple USB
devices (typically low-speed peripherals such as mice, keyboards, printers, and computer speakers). The
C/Port APR Family and the C/Dock Expansion Station Family docking solutions have two USB connectors.

DualPoint integrated pointing device resumes operation in standard PS/2 mode, which means that many of
the configuration features are disabled.
If you are using a PS/2-compatible mouse that is not made by Microsoft and the mouse does not work
properly, reboot the computer. If the mouse still does not work, install the drivers from the diskette or CD that
came with the mouse and reboot the computer.
You can use the computer's keyboard and an external keyboard at the same time. When you attach a
keyboard to the computer, the embedded numeric keypad is automatically disabled.
