That is usually in what they call the "chipset" driver package.
I just cleaned a hp g6 2312 for win 8 because it was driving there..so now i need drivers for windows 7 64 bit to this hp.
Most of the drivers on the hp site was working, but i am stuck now. i Need drivers for the USB ports.
Its in the hardware list with a yellow ?
and i cant find any usb drivers..
