745 MT, HR330 motherboard, USB 2.0 header?

Does my motherboard have a usb 2.0 header? Was contemplating buying this network card and the bluetooth plugs into a header.

The usb header is called Flex Bay connector  #11

Which means this likely works.

Pin 07 - Port 2 GND               (Black)
Pin 08 - Port 1 GND               (Black)
Pin 09 - absent
Pin 10 - Shield/Ground.
 
The header on the mobo is a 5 row x 2 column header and is labelled on the circuit board with Pin 1 being top left, Pin 2 top right, Pin 9 bottom left & Pin 10 bottom right.
 
The above pin-outs therefore mean that the USB2 connections take the left hand column of pins, and those for USB1 the right hand column.
 
I think that its close to the standard Intel USB header layout YMMV.
