Steinberg driver not runnable

Hello, I wanted to run the Steinberg USB Driver YSUSB_V1910-2_Win after installation, but then there appeared the hint “Device could not be opened”. Does somebody know, what the reason could be? I have Windows 8.1 und I’m using Steinberg Elements 9. Thanks for information.

This driver is for Steinberg or Yamaha hardware audio interfaces.

You would be better to post getting started questions in the general forum…more people will see them and be likely to respond there.
This one is more geared towards actual software bugs.
