The surface type cover filter device was missing in device manager, only the HID keyboard device is listed. My type cover worked well when tested on my friend's surface pro 3 while his still failed to work on mine which means is a software problem on mine. I did this and got my HID keyboard Device to update into 'Surface Type Cover Filter Device' but the keypad and trackpad still dont work. It will light up if I press any key. And the keyboard does work in the bios, entered by holding down power and vol up, but doesnt do anything but light up after windows loads. Select Keyboards (in your case Other Devices) Touch and hold over 'Surface Type Cover Filter Device”. Select Uninstall Driver Software (Please DO NOT check the box saying “Delete the driver software for this device”) Follow instructions. Restart your Surface. Tell me if it then works please.
Surface Pro 3 Surface Type Cover Filter Device
Type cover keyboard is not working only the damn touchpad. In device manager i have exclamation mark - unknown device and it was Surface Type cover filter device, however, i couldn't install a driver for it from a Device manager.
Sometimes install of the type cover filter device ends with error code 1 and sometimes it says it's installed (Tried manual and automatically from the internet), but in the device manager it still says Unknown and i am not able to use my type cover keyboard, besides touchpad.
MS totally screwed up my SPro2 with that update.
Any help would be appreciated!
