UMBus Root Bus Enumerator - Unknown Device
Hi there,
I tried to install a wireless Logitech keyboard/mouse combination. The keyboard works fine, the mouse doesn't. The device manager shows the "UMBus Root Bus Enumerator" as unknown device. I researched in some forums and found this: "sc config umbus start= demand". But it doesn't work.
In this forum I found an older threat with this post:
Go to Device Manager > Action > Add legacy hardware > Next > Install the hardware that I manually select from a list > Next > click on "System Devices" > Next > then under "Manufacturer" click on "Microsoft" then under "Model" click on "UMBus Root Bus Enumerator" > Next > Next
But when I want to install legacy hardware, the software asks for a storage device with the drivers. The installation DVD doesn't work. What to do?
Any help is appreciated.
