Bluetooth Passthrough to Virtual machine ASUS MB

Is there a way to pass through the built in Bluetooth on my ASUS motherboard with an Intel CPU to a virtual machine. I assume it comes through as a PCI device, but if that is the case it is not obvious which one. How do I identify the device and how to pass it through to a virtual machine if this is possible?

Assuming that your motherboard supports virtualisation & pcie passthrough, & that you’ve enabled relevant settings in BIOS:

  1. In shell type in lspci that’ll list the available PCI devices.
  2. See if anything in there can be identified as a bluetooth device
  3. Go to your VM, in “Virtualization” & select it
  4. Go to “Devices”, click 'Add", make type “PCI Passthrough Device”, add the device ID
  5. Attempt to boot the VM
  6. If it does work & device boots, attempt to download & install drivers

Odds of success vary.

Headsup; same device that does bluetooth usually does WiFi as well. So hopefully you’re not connecting your NAS over wifi & trying to pass the WiFi card through to your VM.

Thanks for the reply.

Looks like it is: ```

Will try that and see what happens.

Good luck man - glad you found it! Naming convention on these is uhh… not always clear to say the least…

I tried passing through that device and it gave me WIFI in the VM, but no Bluetooth. I am running Ubuntu in the virtual machine. Wondering if there is another device or something that I need to pass through.

Stupid question, but I’m 75% sure that same card gives bluetooth & wifi - did you try installing the bluetooth drivers?

Quick google-fu also advises that there is a chance bluetooth portions identify as a ‘usb device’ becauses it uses the USB bus? Never heard of this, but also never tried. If you’re not using USB for anything worth giving a try?

lsusb -t
or
lsusb

I had some other ones that also quoted checking random USB devices, this is just the most extensive one I found.

lsusb don’t seem to be installed on TrueNAS, but after sifting through dmesg log I finally thought to look at the device list presented when adding a USB device to the virtual machine. One of them was listed as Intel. Added that, and it works. Thanks!
