2.11 Connecting USB and PS/2 ports

This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices.
The location of these ports is shown in Figure 6 above. Note that, for this
board, the PS/2 mouse port is the upper PS/2 port, and the PS/2 keyboard port
is the lower PS/2 port.
The PS/2 connectors are probably quite familiar to you. The USB connectors,
however, may be foreign. The USB (Universal Serial Bus) is a versatile port.
This one port type can function as a serial, parallel, mouse, keyboard, or
joystick port. It is fast enough to support video transfer, and is capable of
supporting up to 127 daisy-chained peripheral devices. Figure 2-23 on the next
pate shows the PS/2 ports on the left and USB ports on the right.
