I have this problem as many others had/have but there is no way to solve it.
I tried all the procedures found on the web, including the installation of Android SDK Manager but without success.
As soon as I connect the KF to my PC, a window opens saying "New Hardware Found - MTP Device".
Then Windows starts asking for the installation of drivers that cannot be found.
And at the end an error message appears saying the device cannot be started (Error 10).
Can somebody help?
I have also tried to connect to different usb ports. The result is always the same.
