Hi Guys,

I'm troubleshooting an issue with one of my USB ports (14) which does not appear to be any of my actual physical USB ports. I made sure of this by plugging in a USB device in every available physical port and they all use different ports.

Using USBView I can see what the issue is but I do not know how I can fix it.
any Ideas anyone?

My best guess it would be a Asmedia USB 3 driver. So try uninstalling it and installing a different version of the Asmedia USB 3 drivers.

I have already tried that. no luck. It is strange because it is an internally assigned port and as far as I can see nothing is actually using that port. I will disable port 14 from the BIOS for now, but it irritates me I cannot fix it. OCD I suppose
