USB Motherboard Cable Assembly Information
|
Although, the following was written using a Belkin
brand motherboard cable assembly, the information generally applies to all USB
motherboard cable assemblies. I personally use and
recommend the Belkin Pro Series Motherboard Cable Assembly Model #F3U001.
USBMan WARNING!
Read This First!
Improperly wiring a USB port can
result in permanent and
fatal damage to the motherboard, the USB port and ANY peripheral connected to
the motherboard.
It is imperative that the specific USB
pin out assignment for your motherboard make and model is obtained from the maker before
any attempt is made to connect the cable to the motherboard. Simply
knowing which pin is #1 is not enough information to properly wire a USB
port. Trial and error will surely result in the destruction of
the USB host controller, the computer system and/or any attached peripheral.
YOU MUST obtain the exact USB pin out assignment from either the motherboard
manual or the manufacturers web site.

Adjust the
Harness to Match
The wires of the cable assembly
can be easily moved to
match the pin out assignment.
Press on the side of the wiring harness at
the indentation next to the wire that you want to move. This will release
the wire from the harness. A straightened paper clip, straight pin or
precision screw driver works well for this
purpose. When you have positioned the wires correctly, secure them in the
harness by depressing the harness tab again. Take care to lift the
tab only enough to release the wire. If you lift the tab too high the
plastic tab will not reset and the wire connection will not be secure.
