Ok - solved this for myself. Tried everything here and elsewhere.
Locked out my surface pro 4 cover keyboard and touchpad even though I know it works fine.
I managed to lock it out with a program called driver booster. Thank you soooooo much Driver Booster !
My solution that worked for me;
You will need to -
A) Be sure that in device manager you see the "surface type cover filter device" driver listed under keyboards.
Your device manager should be like -
Devices:
---blah Devices
---blah More Devices
----Keyboards;
HID keyboard driver
HID keyboard driver
Surface type cover Filter Device (a driver)<------this needs to be showingExcuse me please (if details not perfect) as doing this from my (bad) memory :)
If you have this you are good to go to part B.
B)
Still in device manager goto Human Interface Devices
Devices:
---blah Devices
---blah More Devices
---Human Interface Devices
heaps of devices
heaps of devices
wacom (anything labelled wacom right at the bottom)<------------------you need something labelled wacom for this fix to work.
Uninstall the wacom driver in Human Interface Devices.!!!!VERY IMPORTANT ONLY DO THIS IF YOU HAVE
A SURFACE PRO 4 (or possibly a 3 but not a 2).
Make sure you delete the associated wacom driver too.
Wait about 30 seconds to a minute. When I was doing all this I had my keyboard connected.
Now to win a cigar :) you go back the keyboard section of the device manager and
by following part B) your computer will delete
the ; Surface type cover Filter Device (a driver) from part A by itself :).
So if after 30 or so seconds you see the computer has deleted Surface type cover Filter Device from Part A) goto part C
C) Still in Device manager (after a few minutes) rescan for new hardware (top menu of device manager) and viola You got your keyboard back.?? I didnt even need to reboot.
The thing is apparently microsoft phased out the Human Interface Device-wacom driver after the surface pro 2.
In my case driver booster installed it. I checked and my surface keyboard cover was linked to a wacom device when I had the issue.
I have no idea if this will help you but good luck to you!
Thanks mate..
I have looking for two days. And fortunately found your comment.
It solved my type cover problem. You are better than Microsoft Support Centre. 😊👍
