Hi Johnny,
There will be an incoming update for Windows that can resolve your concern with your keyboard. Generally, cumulative updates are released every second Tuesday of the month. For the meantime, you can run the Surface Diagnostic Toolkit to check for possible software issues.
We'll keep an eye out for your response.
Regards.
I have been at my wits end for several months with my Type Covers not working issues, to the point of having to rely on a poor 3rd party BT knock off. I ran the Diagnostic Toolkit again after seeing this message, not expecting anything but lo and behold here I am typing on my TC4 without issues.
I'm still sceptical that it a) was or what fixed it or b) that it will last but one can only hope.
Fingers crossed the upcoming update will resolve all issues for good.
Spoke too soon. Nearly got through the whole day but eventually USB not recognised error popped up again and I'm back to square one. So frustrating....
