i have been trying to resolve an issue with a usb driver for a gps device i have. Someone suggested uninstalling the usb controller drivers and letting windows install them for fresh. This indeed happened but since that point my computer (surface pro 3) would not connect properly to the type cover (keyboard). It complains that the drivers for the keyboard are not installed properly even when i reinstall them. It also complains that the bluetooth device drivers are not working properly. Any ideas on how to resolve this issue?
