MSI_Z77A-gd55 ports for front panel USB?

Gents:

I just partially updated a legacy AMD/ASUS system with an INTEL 1240.v2, MSI_Z77A-gd55 and 16-Gig Crucial ram. Works mostly just fine under UBUNTU_12.04.

The case is a no-name_2001 full tower with two front panel USB ports that I never connected! After the upgrade I want to connect them. I tried, at mobo pins **JFP2** ... and the speaker works, but not the USBs ... zero response from them so wrong guess! Two dangling spare wires labeled +/- 5 volts!

BUT! I find no obvious mobo ports for the case-front wiring harness: that is nothing in the mobo manual points to a couple mobo-pins and says "front panel USB connectors". Can it be I must use the **JUSB1** connector meant for an add-on rear-unit? BTW: are all ( 1-->3) UBS wiring harnesses compatible? Any comments appreciated.

page 1-6 and 1-7 of motherboard user manual show you that jusb 1 to 3 are usb 2.0 connector the jusb 4 is for 3.0 usb connector so use the socket one first then 2 after 3 if needed for usb http://www.msi.com/service/download/manual-18016.html

Thanks Scout_03:

Yes, on JUSB! I see the header pins for +5 volts and grnd : I did **not** connect those harness wires ... expect to find the +/- D guys hanging around.

Appreciate your advice.
