Typical Motherboard USB Pin-out Header
The typical internal USB Pin-out Header found on
motherboards consists of 9 pins arranged in 2 rows; each
header provides 2 USB ports. Match up +5VDC (Pin 1)
on the USB Cable Connector to Pin 1 or Pin 2 on the
pin-out header. Connecting the USB cable improperly
may damage the system. Please refer to your system's
manual for proper connection.
