having the possibility to identify the fixing commit would indeed be
nice, but I can understand knowing 6.11.5 fixes the issue this looks
like additional unnecessary work.

Do you maybe can share dmesg information from booting with the old
kernel with the controller available?

I wonder if this might be related to 2c1dda2acc41 ("Bluetooth: btusb:
Fix regression with fake CSR controllers 0a12:0001") which was
backported to 6.11.5.
