After updating to windows 10, I have an unknown device in the device manager. I have tried letting Dell system detect upgrade the drivers but it doesn't seem to notice the unknown device.
Any ideas on figuring out which device is unknown? (no additional hardware is connected to the laptop).
Is it possible it is the freefall sensor since I did not add it (the last time I tried to upgrade, it caused some erratic behavior of the touchpad so I reverted back to Windows 8. When I upgraded again, I didn't download the freefall driver..
