Facing the same issue, also on an intel NUC.

Please check host and supervisor logs. I suspect there will be more information there.

I also had this very same issue, However I got it working (HA 2025.5.2), I entered the BIOS of the NUC and disabled Bluetooth, ran HA and deleted the failed intel Bluetooth integration and did a restart. Then did a complete shutdown. Re-entered the BIOS and turned Bluetooth back on. When I restarted HA it had discovered the Bluetooth, I added the integration and now all is working fine.

I am using HA OS as VM on unraid, and I have the same issue. Tried to not pass through the BT device, restart, then pass it through again, no luck.

I have somewhat the same issue, I'm running proxmox with bluetooth passthrough on a NUC 15 Pro (i3).

Before enabling thunderbolt support it all worked fine, but I need this for my USB SSD to get recognized. After enabling that, the passthrough still works, I can also see the device appear in Home Assistent, but it does not get recognized as a bluetooth adapter anymore. Resulting with the same GUI message as OP.

Disabling in BIOS -> Start and remove in HA -> Enabling in BIOS as suggested here, did not work for me. I do see these log messages in Host:

Does anyone have an idea how to solve this?

EDIT: Solved it myself, in my case Proxmox was trying to use the device itself. Solved it with these commands in Proxmox:

echo "blacklist btusb" > /etc/modprobe.d/blacklist-btusb.conf
update-initramfs -u
reboot
