From Microsoft support site:
The device is installed incorrectly. The problem could be a hardware failure, or a new driver might be needed.
Devices stay in this state if they have been prepared for removal. After you remove the device, this error disappears.
Remove the device, and this error should be resolved."
Try to reinstall drivers here.
If this won't help then uninstall Your current driver for touchpad and install latest driver for it from here. There is now avaible version 188.8.131.52.
