Thanks for the verification. I never tried hibernating my Surface Pro. I either turn it off or put it in sleep mode. This concern will not happen for me in sleep mode. I used to have 5 Keyboards listed in the Device Manager but now I only have 4. I don't have one of the Locations. All the Drivers are dated pre first Surface Pro setup.
Presently, I have given up trying to resolve this. I am still deciding what I will do. I have a week left to return the keyboard and/or Surface Pro. The last communication I had with business support regarding the keyboard was to return the keyboard although they said communication with engineering said it was a driver issue.
I found the easiest way to get around this is to just delay folding the keyboard over the display for a few minutes and it will start with the keyboard enabled (desktop mode). I relayed this over 3 times to support but they still keep on insisting I should unmount and mount keyboard. to make the keyboard function. Like, how long will the keyboard last if we unmount and mount it daily? I find it is far easier to remember to delay folding the keyboard over the display.
Just a note, as both retail and business support communicated. If the keyboard or Surface Pro is determined defective you will get a refurbished keyboard or Surface Pro in return. The only way to get a new item is to return either/both before the 60 day return period and repurchase.
