Lets get a fresh start,
In order to make sure the Keyboard is well not detected, please do as follow:
For Windows Only,
When you plug the MiniLab the first time, you are supposed to see a little rectangle in bottom right of your screen, that says if the driver is installed or not.
1/ Open the Control Panel
2/ Under Audio and Material open the device Manager
3/ Deploy the usb bus controller
4/ Plug and unplug your MiniLab several times (the list is supposed to refresh)
If still a problem, try with another usb port, or with another usb Cable.
