Hello,

I bought a new case about a week ago and tried it's USB ports..
All worked but one of the USB3 headers didn't..
So I checked the cables, checked everything.. Decided to remove the USB3 plug from the MOBO and what do I see?
2 Pins are missing!

I have no idea how or when.. I tried to search for them, maybe they snaped when I unpluged the cable, but I didn't find anything..

The missing are pins 1 and 2 in the picture..
I think that pin 19 is missing too.. The image kind of faded off my mind right now..

Are those pins the reason why one of the USB3 ports won't work?
What do they mean? What do they do?
Is it safe to even keep the cable connected to the MOBO without those pins?

Thanks.

Pin 1 is power, pin 19 is power and pin 2 is the USB 3 RX- signal, so yeah that's the reason the ports won't work. I can't see any harm in leaving it plugged in.

Only one port out of two doesn't work.
Does it make sense?

The setup is a mirror image (left to right with ID being the over current protection) so pin 19 must be making. If that one port is working then you should be OK using it.

Check in the sockets on the cable to make sure the pins aren't stuck in there, you don't really want them contacting intermittently.

I checked, didn't see anything..
Man... that's so annoying.. No idea what happned to the pins.
This MOBO is a second hand but I was sure I gave it a super good check.. But again.. how could I break it?
Hope those pins aren't anywhere near contact points waiting to make a short circuit.

Thanks anyway mate.. :(

If you're worried that the pins are still in there somewhere give the rig a good look over, but I think if they were still in there and were going to short something they would have done by now. Chances are they were missing when you got the board.

If you're satisfied could you mark the thread as solved please mate?
