I have installed windows 7 on my Toshiba Qosmio x505 and have installed all the required drivers as well. The problem is that when I am opening Devices and Printers then I am informed for troubleshooting the system. When I try to install the driver for the unknown device then it says no driver found, I really don’t know if I really need the driver or not as I am not having any issues with the same. Since I have installed all the required drivers I want to install driver for the unknown device as well. Is there anyone who can help me find out to which hardware is the driver related?? Any help regarding this will be appreciated.
