If anyone wonders what USB Bluetooth 5.0 dongle to works on FreeBSD for a small amount of money (below 20EUR) ASUS USB-BT500 seems to work fine with ng_ubt out of the box :-)
There is even half cheaper usb dongle out there from Asus but I did not try that one.. however assuming BT4.0 radio on my laptop worked fine it should work too.. I may try that one as well if anyone wants to :-) I have audio (using virtualoss and even pulseaudio) on my bluetooth headset :-) Did not make microphone and buttons work yet but that may be a matter of better configuration :-) BIG THANK YOU to USB + Bluetooth + Virtual OSS developers!! :-) -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
