Hi, I have found the solution. If you go in device manager, click on the pci simple communications controller, go in property and then go in details. You will see a code like per example PCI/VEN_8086&DEV_27D8&SUBSYS...
The VEN code means vendor and the DEV code means device: in my case the vendor is 8086 and the device is 27D8.
Once you have the two codes, go to http://pcidatabase.com/
. Enter the two codes and you should get the name of your
hardware. From there you can search for a driver download for your hardware.
In my case the pci simple communications controller was a Microsoft UAA Bus HD audio. I also had another pci
device that didn't work properly, using the same method I found out that my pci device was an HSF PCI internal modem with code number CX11252-11. I had a hard time downloading one of the drivers, after 6 or 7 times the download started so be patient if you have the same hardware
NOTE: to access the device manager, go in control panel, then performance and maintenance, system, hardware and finally device manager.
