Hello Community,

i´ve problems with my new USB controllercard Startech_ PEXUSB3S44V.

Under windows 10 without using unraid it works without issues, but in the VM the device-manager says that the card is not able to start ( Code 10).

 

Syslog:

May 25 13:47:56 Tower kernel: DMAR: [Firmware Bug]: RMRR entry for device 0e:00.0 is broken - applying workaround
May 25 13:47:56 Tower kernel: DMAR: [Firmware Bug]: RMRR entry for device 0f:00.0 is broken - applying workaround
May 25 13:47:56 Tower kernel: DMAR: [Firmware Bug]: RMRR entry for device 10:00.0 is broken - applying workaround
May 25 13:47:56 Tower kernel: DMAR: [Firmware Bug]: RMRR entry for device 18:00.0 is broken - applying workaround

 

 

It also doesn´t work with the startech driver.

Can anyone help me with this problem? I

 

 

Here is my Hardware:

Mainboard: X99-e/USB3.1

GPU: HD5450 and RX 460

CPU: i7-5930K

RAM: 32GB Corsair Vengeance 3000

PSU: Corsair RM850i

Controllercard: PEXUSB3S44V

I get similar errors on my two Innatek USB3 cards, but they seem to work in spite of the warnings.  I'm wondering if it contributes to some of the system stability issues I see around USB.  Here's what my errors are on bootup:

When I launch a VM, I get another virtlog error about not able to map the BAR on the USB device.  I don't have it handy, I'm afraid.
