The mainboard supports up to 6 USB ports. USB allows data
exchange between your computer and a wide range of
simultaneously accessible external Plug and Play peripherals. You must
have the proper drivers installed in your operating system to use the
USB ports. Refer to your operating system’s manual or
documentation.
Two onboard USB por ts (CN1 - Black) are located at the ATX
double deck por ts of the board.
Depending on the type of USB port cable that you are using, the
J17 and J19 connectors on the mainboard allow you to connect 4
more optional USB ports. These optional USB ports, which are
mounted on a card-edge bracket, will be provided as an option. If
you wish to use the optional USB ports, install the card-edge
bracket to the system chassis then insert the connector that is
attached to the USB port cables to J17 or J19.
Insert the USB por t cable connector to pins 1-10 if:
• One of the holes on the cable connector is plugged, meaning the
cable connector has a keying mechanism.
Insert the USB por t cable connector to pins 6-15 if:
• None of the holes on the cable connector is plugged, meaning
the cable connector has no keying mechanism.
The system board supports the Wake-On-USB Keyboard function.
This function allows you to use a USB keyboard to wake up a
system that is in the S3 (STR - Suspend To RAM) state. If you want
to use this function, make sure “USB Resume from S3” (“IRQ/Event
Activity Detect” field) in the Power Management Setup submenu of
the BIOS is set to Enabled. Refer to “USB Resume from S3” in the
Power Management Setup section in chapter 3 for more information.
