download pci simple communications controller driver windows 7 toshiba c640 help me
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 www.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.
