Unknown USB Device

Hi,
I have a problem with the USB of the Rift Headset. When I plug it in, I get a message, that the latest USB Device is unknown and the port couldn't be restarted (something like that)
It is only with the usb cable of the HMD. Everything other works.

But the best: Oculus is working well. Games are displayed within etc.

But how to fix this error. I have a yellow exclamationmark in device manager "Unknown USB Device" In Oculus software, everything is correct and green marked.

Hey FormelLMS, if
you haven't already, try different USB 3.0 ports. I also recommend
reinstalling your USB drivers and the Oculus drivers. You can install
the Oculus drivers by closing the Oculus app, go to C:\Program
Files\Oculus\Support\oculus-drivers, and opening oculus-driver. I
also recommend disconnecting other USB devices except your Rift
hardware and mouse/keyboard. If your Rift is working fine, I wouldn't
be too concerned but please feel free to create a support ticket at
https://support.oculus.com
if you need more help. Thanks! -Rick

Hi Rick, thanks for your answer. 
I've tried every single usb port on my PC. Onboard and on my Inateck Card. Updated all drivers and reinstalled the whole windows. 
I've let the driver installer run as you said. It takes ten seconds where I can see it in Taskmanager but no GUI. Is that correct?

In the end it doesn't work unfortunately. I believe, that this problem comes with 1.35. Before I didn't have had this problem. 

I've opened a ticket on Thursday . I've heard nothing until now. Hoping that there will be a fix
