Canīt believe nobody has posted a solution for this problem yet. It seems to happen on every model of arturia controllers ( Keystep, Beatstep, and Pro relatives). Been looking everywhere on the internet if somebody found a solution and gave up after a couple hours... Midi CC was not recognizing my Keystep Pro, Ableton wasn't either, then i thought it could be something about the drivers on windows, as i've had some past experiences with other devices such as the Korg Modwave. It seemed weird as they are different devices but i wasn't too wrong about it.
I openned windows device manager and found this weird thing with an error sign on other devices, it was named unknown device and it went off when i unplugged my KSP and back on when re connected it. So i clicked on update controller, then i just had to select search for controllers automatically and it worked. Im still having that error sign on it and it stills name it unknown device but now my Midi CC and Ableton are showing the device and working properly.
That was the solution for me , if it didn't worked for you i'm not sure what could be causing it. Maybe an error during the installation of the Midi CC wich also installs the Arturia midi driver.
I hope this to be helpfull for someone , sorry if i didn't expressed something correctly, I am native from Spain.
