The night before, I attached a usb keyboard and mouse to my 2nd gen x1 tablet. But, the next morning, when I attached the keyboard on the module again, it is not recognized. I checked the device manager and I do not see any USB Composite device shown in USB controllers with the keyboard attached. I have also updated the tablet through lenovo vantage and the problem still persists. Any and all help would be greatly appreciated!
