Worked for my as a workaround on MC 8.6.1  with MOJO DX. All glory to your head, zonik, you saved my sanity.

Did anyone have a good solution for this apart from restarting or disabling / enabling the driver?

Disabling windows fastboot can resolve this issue

Many thanks.

I had to disable fast boot in the BIOS AND in windows - that did the trick.

I also had this issue after upgrading to windows 10.

The solution Yoruba describes about changing the power options has solved this issue for me on all my workstations that I upgraded to windows 10.
