USB header on ThinkCentre M55 8808-CM8 not working.

[ Edited ]

I have a ThinkCentre M55 8808-CM8 and in the very part of the upper left corner is a USB header.

 

Here are 2 images.

 

A close up one.

And zoomed out one also showing the riser slot.

The images show that right next to the USB header is a JP6 which to me from past experience means Jumper 6. My question is this. Do I need too short this jumper before the USB header will work? I don’t have a motherboard manual for this system and the ones on Lenovo support site don't even mention anything about a USB header. I plugged in a USB bracket that goes in a card slot and connected it to the header and got no response on any USB device i plugged in there. I'm afraid i may fry the board unless I’m absolutely sure that JP6 needs to be shorted for the header to work.

 

Thanks in advance for any info. If anyone knows of a more detailed manual for this board that would also help. Thanks!

The second graphic HERE shows the pinout for 12-pin headers. JP6 does mean jumper #6, but it refers to the entire header, not just that one pin.

I don't understand why there is a USB header and it is not working. I have 2 computers exactly the same and it doesnt work on either one. Anyone know of a specific motherboard manual for this pc with the USB header identified? All I can say is that on the board it says Bristol-A Rev 3.3 (second pic above).

The second graphic in the link is not what I have. On my header pin 2 is marked on the same side as the rest of the 5 pins for the 12 pin usb header. On the graphic it shows pin 2 on the side with the other 4 pins and the last one missing.

i have tested this usb header for you on my Thinkcentre M55 8800-A31, and it works.

Do you have all the usb ports enabled in your bios menu?

Is your usb header in the same place mine is? Another words we have the same board. Looking from the front of the pc mine is in the upper left corner under the riser card. Its in the pictures.

Re: USB header on ThinkCentre M55 8808-CM8 not working.

But its actually weird for a pc to have 10 total usb ports (if I get the header to work). Usually I seen 4, 8, 12 on newer computers not including usb3 as those may have a separate controller. Maybe the port is inactive because I have the fingerprint reader disabled in bios but I'm not sure if fingerprint reader uses the internal usb header or the serial header.
