Installation
WARNING! PCI Express cards, like all computer equipment, can be severely damaged by static
electricity. Be sure that you are properly grounded before opening your computer case or
touching your PCI Express card. StarTech.com recommends that you wear an anti-static strap
when installing any computer component. If an anti-static strap is unavailable, discharge
yourself of any static electricity build-up by touching a large grounded metal surface (such as the
computer case) for several seconds. Also be careful to handle the PCI Express card by its edges
and not the gold connectors.
Hardware Installation
1. Turn your computer o and any peripherals connected to the computer (i.e. Printers, external
hard drives, etc.). Unplug the power cable from the rear of the power supply on the back
of the computer and disconnect all peripheral devices.
2. Remove the cover from the computer case. See documentation for your computer system
for details.
3. Locate an open PCI Express slot and remove the metal cover plate on the rear of the
computer case (Refer to documentation for your computer system for details.). Note that
this card will work in PCI Express slots of additional lanes (i.e. x4, x8 or x16 slots).
4. Insert the card into the open PCI Express slot and fasten the bracket to the rear of the case.
5. Connect an LP4 molex power connector from the computer power supply to the LP4
connector on the card. An LP4 to SATA Power adapter cable in included, if only SATA
Power connectors are available.
NOTE: The LP4 power is optional, as the card can draw power from the PCI Express bus,
however the amount of power is limited. It is recommended to have the LP4 power
connected when possible, to ensure that all USB peripherals are able to receive the full
amount of power available.
6. If connecting an internal USB device or front panel port (single), connect the USB header
cable to the header connector on the card, located just behind the top external USB port.
The +5V pin is marked with a triangle (see photo on previous page).
NOTE: This will disable the adjacent external port.
7. Place the cover back onto the computer case.
8. Insert the power cable into the socket on the power supply and reconnect all other
connectors removed in Step 1.
Driver Installation
No driver installation is required for supported operating systems, as this USB 2.0 adapter card is
natively supported, so the drivers are already installed.
