Hello,
I upgraded my XPS 9343 to Windows 10 and run several times the driver update "wizard" from the Dell support website (and also I re-installed manually all the latest verison of drivers from the "Find yourself" link and re-run the driver update wizard for an additional check).
Thus, according to the Driver update wizard and to windows Update my PC is up-to-date: I also tried "uninstalling" the device from Device Manager rebooting the PC, but without success.
Nonetheless, I still have an "unknown device" on the Device Manager (from control panel).
Any suggestion ?
