Sometime 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.

Your Surface may be unable to communicate with the Type Cover after installing the update. You can try booting the device from UEFI to see if the accessory will work. Doing this will help us check if the Type Cover works before the Surface loads Windows. To get to the UEFI, follow the steps here.

To update your Surface with the latest drivers and firmware from the Download Center, select the.msi file name that matches your Surface model and version of Windows. For example, to update a Surface Book 2 with build 15063 of Windows 10, choose SurfaceBook2Win100092.msi.

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.
