Other Connection Options
USB provides simpler plug-and-play connectivity and enhanced performance. If you
don’t have any available USB ports, try the following options.
USB hub
If all of your USB ports are in use, consider purchasing a 4-port or 8-port USB hub.
USB hubs, which are available at office and computer supply stores, provide an
inexpensive solution for connecting multiple USB devices when your computer has a
limited number of USB ports.
PS/2 connection (Windows only)
Although we recommend connecting using USB,
some Microsoft wireless desktop sets provide a
PS/2 connection option. Use a PS/2 connection
only if you don’t have any available USB ports.
1 Shut down and turn off the computer.
2 Plug the purple PS/2 connector into the
computer’s round PS/2 keyboard port.
3 Plug the USB connector into the green USB-to-
PS/2 adapter, and then plug the adapter into
the computer’s round PS/2 mouse port.
