Hello FreeBSD (BabaOS) community,

I'm experiencing issues with a Bluetooth USB dongle on my FreeBSD system and need your help.

System details:
FreeBSD 14.2-RELEASE releng/14.2-n269506-c8918d6c7412 GENERIC amd64

Hardware:
Cambridge Silicon Radio Bluetooth Dongle (HCI mode)
Vendor ID: 0x0a12

The device is detected by the system:
```
ugen4.2: <Bluetooth Dongle (HCI mode) Cambridge Silicon Radio, Ltd> at usbus4, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA)

ubt0 on uhub3
ubt0: <vendor 0x0a12 USB2.0-BT, class 224/1, rev 1.10/88.91, addr 2> on usbus4
```

All necessary modules are loaded:
- ng_ubt.ko
- netgraph.ko
- ng_hci.ko
- ng_bluetooth.ko
- ng_l2cap.ko
- ng_btsocket.ko

Issue:
When trying to start the Bluetooth stack using:
`/etc/rc.d/bluetooth start ubt0`
I get the following error:
`/etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0`

Questions:
1. Has anyone successfully used this specific CSR dongle with FreeBSD?
2. Are there any known issues with CSR dongles on FreeBSD 14.2?
3. What additional debugging steps would you recommend?
4. Could someone share a list of confirmed working Bluetooth dongles for FreeBSD?

I've already verified that all necessary kernel modules are loaded. Any help or guidance would be greatly appreciated.

Thank you in advance.

Thread 'non-working bluetooth dongle - Dezen DZ-BTUAV5'

I recently bought a cheap bluetooth dongle (because it was cheap, and I was buying other things): Dezen Bluetooth 5.0 USB, Mini adapter. Part number on the back of the packaging is DZ-BTUAV5. Plugged into a workstation that runs FreeBSD 13.4-release-p2
Code: 
root@kg-core2:~ # freebsd-version -ku
13.4-RELEASE-p1
13.4-RELEASE-p2
root@kg-core2:~ # uname -a

Have you tried other devices? I need to know exactly which ones work and on which OS version, and which ones don't. The information here isn't always accurate - I remember with MacBook, they wrote that WiFi definitely works, but in fact it didn't. I've been caught by misleading information on this site several times already.

Buying equipment just for testing requires quite a bit of money, and it's actually foolish to adapt OS to hardware - we should choose hardware that's compatible with our OS. I've already decided on my OS, but these kinds of issues are very disappointing.
