Beaglebone Black driver troubles


I am trying to get a Beaglebone Black working on a Windows 8.1 machine. ( I managed to get it working on a Windows 10.1 machine at work.)

I googled the problem and all that I find is the signing of the driver issue. I did follow the procedure to install unsigned drivers on both machines.

In my device manager I see the ‘Linux USB Ethernet/RNDIS Gadget’ under Network Adapters on my machine but with an explanation mark. The status is*:This device cannot start. (Code 10) {Operation Failed} The requested operation was unsuccessful.*

Any advice will be appreciated.

Thanks in advance
