Surface Type Cover Filter Device Hidden

Surface

I have tried doing a restart, hard restart, uninstalling the existing keyboard drivers and clicking on scan for hardware changes, but the surface type cover filter device doesn't come back. Install Microsoft Surface Type Cover Filter Device driver for Windows 7 x64, or download DriverPack Solution software for automatic driver installation and update.

Surface Type Cover Filter Device Pro 3

hi all,
i have a surface pro 3 with a type cover 4 (i got the surface pro4 type cover) running windows 10 and the type cover is no longer being recognized out of the blue.
I have tried many troubleshooting methods, but none have worked so far.
I opened device manager and i noticed the only keyboard category driver i have is the HID Keyboard. Looking in other threads on this issue, it seems i should have a driver for 'Surface Type Cover Filter Device' or for 'Surface Type Cover'
Does anyone know where i can find the driver for the type cover 4?
Troubleshooting steps i already initiated and none of them have worked so far:
* unclicked and reclicked the keyboard many times, while connected to the internet
* did a two button shutdown/reboot
* brought the computer up to date on windows update, did reboots, shutdowns, nothing
* reset the laptop (while maintaining all data) and then installed windows updates again + some more reboots
* installed the latest 'SurfacePro3_Win10_10586_1702002_0.msi' drivers & firmware pack for surface pro3 from Download Surface Pro 3 from Official Microsoft Download Center
* *tried* to install the latest 'SurfacePro4_Win10_15063_1702001_0.msi' drivers & firmware pack for surface pro4 from Download Surface Pro 4 Drivers and Firmware from Official Microsoft Download Center but it did not work since i have the surface pro 3
i cannot get the driver to show up anymore, and given that i never uninstalled or deleted it, i don't know what else i can do.
I am traveling and don't have access to a microsoft store to purchase a new keyboard so i am stuck and i would appreciate any help in further troubleshooting or locating the proper driver for the keyboard.
thanks in advance!
