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 youāve enabled relevant settings in BIOS:
- In shell type in
lspcithatāll list the available PCI devices. - See if anything in there can be identified as a bluetooth device
- Go to your VM, in āVirtualizationā & select it
- Go to āDevicesā, click 'Add", make type āPCI Passthrough Deviceā, add the device ID
- Attempt to boot the VM
- 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 youāre 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 uhhā¦ not always clear to say the leastā¦
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 Iām 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 āusb deviceā becauses it uses the USB bus? Never heard of this, but also never tried. If youāre not using USB for anything worth giving a try?
lsusb -t
or
lsusb
Form in question: Motherboard Bluetooth Passthrough UnRaid 6.4 to Windows 10 VM? - VM Engine (KVM) - Unraid
I had some other ones that also quoted checking random USB devices, this is just the most extensive one I found.
lsusb donāt 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!
