Not my domain of expertise but:
(a) which ersion of FreeBSD are you on?
(b) Check if you have an 0x0026 entry in /usr/src/sys/netgraph/bluetooth/drivers/ubt/ng_ubt_intel.c:     { USB_VPI(USB_VENDOR_INTEL2, 0x0026, UBT_INTEL_DEVICE_8260) },
(c) did you install firmware?  There is an iwmbt-firmware package.  Looks like you have.

(d) last time I tried I with an AX210 I had to try to start it 1..4
times until eventually it worked.

Reading below I think you are in the (d) category.

Here's notes I left someone else for that trial:

------------------------------------------------------------------------
I installed the iwmbt-firmware package manually and then manually loaded
it, twice; the 2nd time with -DI and then started
/etc/rc.d/bluetooth start ubt0
one more time and then it was there..

[337612.962319] ubt0 on uhub0
