           Summary: Bluetooth not working on bhyve guests

           Version: 14.0-RELEASE
          Hardware: Any
                OS: Any

Hi, 

I setup bhyve by bhyve-vm. Host is FreeBSD 14.0-RELEASE. One of my guest is
running FreeBSD 14.0-RELEASE. Here I would like to use a Bluetooth adapter to
connect to my speakers. For this I passthrough the following: 
ppt2 2/0/0 Yes 400 Series Chipset USB 3.1 xHCI Compliant Host Controller to the
guest.

Upon running the Guest the Bluetooth adapter is recognized: 
#dmesg | grep ubt0
ubt0 on uhub1
ubt0: <vendor 0x0a12 CSR8510 A10, class 224/1, rev 2.00/88.91, addr 1> on
usbus0

I continue to setup Bluetooth by following this guide:
https://freebsdfoundation.org/freebsd-project/resourcesold/networking-basics-wifi-and-bluetooth/. 
# service bluetooth start ubt0
/etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt0
# service bluetooth start ubt0 - OK!

I can't setting up Bluetooth! Something is missing.

Facts: 
1. If I pass the controller on my other guest which is running Windows10 then
Bluetooth is working - which means passthrough is working. Only in FreeBSD is
not. 
2. In past I used FreeBSD 14.0-CURRENT only and the adapter worked many many
months - so the adapter is not broken.
3. I also have a wireless adapter - passing to guest is ok, setting up as AP is
ok but no wireless transmission. 

Best regards,
