bluetooth dongle - Trust Myna Bluetooth 5.3 Adapter

T

tingo

Yes, another cheap bluetooth dongle. this time it is the Trust Myna Bluetooth 5.3 Adapter, article number 25329.
It test it on a machine running FreeBSD 14.2-release-p2:
Code: 
root@kg-starone:~ # freebsd-version -ku
14.2-RELEASE-p1
14.2-RELEASE-p2

root@kg-starone:~ # uname -a
FreeBSD kg-starone 14.2-RELEASE-p1 FreeBSD 14.2-RELEASE-p1 GENERIC amd64
In /var/log/messages, I can see

the device descriptor looks like this

I have no idea why FreeBSD wants to identify it as "Realtek Bmuuuooth" on this machine.
hccontrol just returns with no information
Code: 
root@kg-starone:~ # hccontrol -n ubt0hci inquiry
Inquiry complete. Status: No error [00]
I'm guessing I need to load firmware, since this is a Realtek chipset. I have installed
Code: 
root@kg-starone:~ # pkg info rtlbt\*
rtlbt-firmware-20240909
but FreeBSD 14.2-release-p2 doesn't have the rtlbtfw program
Code: 
root@kg-starone:~ # which rtlbtfw
So, not working today, but might work in the near future.

FWIW, on a different machine
Code: 
root@kg-core2:~ # freebsd-version -ku
13.4-RELEASE-p3
13.4-RELEASE-p4
it is recognized properly
