I updated the BIOS on my GA-965P-DQ6 to version F6, and now I have an Unknown Device in Windows, a “PCI Simple Communications Controller” . Windows can't find a driver for it.

The only card I have is an ATi x1900xtx. I don't have a modem, or anything like that. I do, however, have a serial port.

So, does anyone have any idea what's going on?

well mine has not repeat not got an entry for that anywhere in the hardware

and i am running F6 as well

As far as I can tell, the the only PCI devices on the board are the southbridge, the audio chip, the Firewire interface, and anything you have in the PCI slots. Has your audio or Firewire stopped working? Do you have the latest Intel INF file installed?

Gigabyte has a new audio driver - which I installed. The audio was working fine anyway.
I can control my camcorder through the firewire port,
I reinstalled Windows,
Applied all the updates,

And I still have this unknown device.

Ok. I fixed it.

I needed the
Intel® Management Engine Interface Driver

Which I got from http://downloadfinder.intel.com/sc [...] l&lang=eng
