Intel AX201 Bluetooth (8087:0026) firmware fails to load in HAOS

Description of the issue

I am running Home Assistant OS 16.2 on Proxmox VM.
Bluetooth adapter Intel AX201 (8087:0026) is detected, but firmware fails to load and Bluetooth does not work.

Logs
Bluetooth: hci0: Firmware intel/ibt-0040-4159.sfi
Bluetooth: hci0: Firmware file: intel/ibt-0040-4159.sfi
Bluetooth: hci0: Firmware Version: 200-48.24
Bluetooth: hci0: Fw download error recovery failed (-19)

Environment

  • Host: Proxmox VE
  • VM: Home Assistant OS 16.2
  • Home Assistant Core: 2025.9.4
  • Device: Intel AX201 Bluetooth (8087:0026)

Expected behavior
Bluetooth firmware should load successfully so that hci0 can be used by Home Assistant for BLE integrations.

Additional info
On Linux distributions (Debian/Ubuntu) this device works fine when the latest linux-firmware package is installed.
Could you please update the firmware blobs in HAOS to include the latest Intel Bluetooth firmware (ibt-0040-4159.sfi / .ddc)?

Hello zetmen123,

If this is on the supported list, then write up an issue. Bluetooth - Home Assistant .

If it’s not on that list it it may not be supported meaning this is expected behavior.

I checked the documentation, and indeed, Intel AX201 (8087:0026) is not on the list of supported Bluetooth adapters. (

The AX201 does work using HAOS, but the issue here is the VM needs to passthrough the entire PCI device. Passing through just the USB device is not sufficient.

Here is my writeup on this subject for QEMU/KVM based VM.
I don’t use Proxmox, so can’t help you on that part.

Hi, did you get anywhere with this? Similar issue with a fresh home assistant install on a Beelink s13 with the AX201.
