Surface Type Cover Filter Device Surface Pro 4

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. In Internet Explorer, click Tools, and then click Internet Options. On the Security tab, click the Trusted Sites icon. Click Sites and then add these website addresses one at a time to the list: You can only add one address at a time and you must click Add after each one. Surface Type Cover Filter Device Driver: Windows uses drivers for all the hardware components it uses. Surface Pro has an additional driver to provide the compatibility of the keyboard (type covers). If it isn’t updated, your keyboard will not work.

My Surface Pro Type cover has stopped working a few days ago for no apparent reason.
I have spent hours on this , cleaning the port, rebooting in UFI, reinstalling windows from the Recovery Image, updating Windows to its latest version, following every possible advise I could find about this subject but nothing has solve the problem.
What I have noticed is that the Surface Type Cover drive are not listen in the Device Manager (see image below). These drives are necessary for the Type Cover to function, but despite updating and rebooting they are not installing again.
Does anyone know of a way of reinstalling these independently. I have downloaded them from a folder but do know know how to add them to the device manager.
ProSometime within the last 1-2 weeks my Surface Pro's type cover stopped working. Device Manager shows a failed 'type cover' device under Other Devices (with an exclamation point on it). I don't think it's a hardware issue because if I hold down Power and Volume Up to get into the UEFI screen then my Type Cover keyboard arrows work fine to navigate the menus.
  1. Per https://support.microsoft.com/en-us...ubleshoot-your-surface-type-cover-or-keyboard I've tried uninstalling it and letting the driver re-install, but it just beeps continuously until I disconnect the type cover and then the Device Manager shows the same Other Devices failed device.
  2. I also tried going to Microsoft Download Center and re-installing the latest Surface Pro drivers software. No change.
  3. I also tried System Restore to go back to a system version from a couple days ago. No change.
