BT module and Unraid USB drive always on same IOMMU / USB controller


Recommended Posts



I have an ASrock x570m Pro4 board and a Intel AX200 M.2 WiFi / BT module installed. Passthrough of the WiFi network controller works without a hitch but I struggle with the BT module... It's recognized as an USB device (via M.2 type E) and added to USB bus 1. The problem is that my unraid USB drive which is installed internally is also added to USB bus 1 and since it's on the same controller, I cannot pass it through my VM. I tried different internal USB ports, the drive is always recognized as being connected to bus 1. I have no idea how to influence where the BT module is connected to, I assume it's fixed on bus 1.


Any idea how to split those two up? I guess plugging in the USB drive to an external port might do the trick, but I don't want to break up my neat build...

Hope someone has an idea!

Thanks, Denis
