Hi, I know this is very weird but I noticed the bluetooth adapter works just
fine if I pass it through a VM using Gnome Boxes, but no matter what I do it
doesn't work on a real machine. On the virtual machine, I'm running OpenSuse
Tumbleweed with kernel 5.15.5.1 (also worked with KDE Neon with kernel 5.11)
and on the host, I have the kernel 5.15.11-200. I have no idea why it can't get
an HCI address on a real machine (check my prior comments) but it can on a VM
with any kernel version.

I hope I'm not spamming this with useless information, sorry if that's the
case.

On the VM hciconfig shows:

hci0:   Type: Primary  Bus: USB
        BD Address: 00:1A:7D:DA:71:10  ACL MTU: 310:4  SCO MTU: 64:8
        UP RUNNING 
        RX bytes:12949005 acl:284564 sco:0 events:91 errors:0
        TX bytes:1460 acl:17 sco:0 commands:56 errors:0

Dmesg on the VM shows:

[  797.515701] usb 4-1: USB disconnect, device number 2
[  821.123684] usb 4-1: new full-speed USB device number 3 using uhci_hcd
[  821.388913] usb 4-1: New USB device found, idVendor=0a12, idProduct=0001,

[  821.395210] Bluetooth: hci0: CSR: Unbranded CSR clone detected; adding
workarounds and force-suspending once...
[  821.395214] Bluetooth: hci0: CSR: Failed to suspend the device for our
Barrot 8041a02 receive-issue workaround


There's also a BTMON log on the VM I'll add after this post as an attachment
because it's too big. Note the log was taken by disconnecting the adapter,
running btmon and connecting it. I have no idea why it's that long.

I hope this can help somewhat.
