Don't use this type of hardware but it should (?) behave as any other BT harware.
eg: BT mouse with a USB receiver plugged in.

There may be more information in /var/log/[fill-in]
ie: [dmesg] and then [kern.log], [syslog], [messages] and [lsusb].

1. Boot the box without the [thinguies/USB whatever] plugged in.
2. Plug them in and check what [dmsg] tells you.
3. That should give you some data wrt the hardware.

Check to see what [lsusb] says.

Maybe it is a driver/configuration/pairing issue.

Edit:
A fast check on-line found that the earbuds have to be paired manually.
The lack of [systemd] in Devuan is (most probably) the key.
Maybe that the Huawei management apps are not Linux-able?

Google for [HUAWEI FreeBuds SE 4 ANC linux] and [HUAWEI FreeBuds SE 4 ANC linux Devuan].

Best,

Huawei Freebuds

Work out of the box in Debian 13. Not so much in Devuan 6. They are connected in bluetooth. But no sound. I can not see where to change the output source. They must not be connected properly. Sometimes when I try to connect I get: Conection unsucessfull - No sound end points registered.( thats my translation)
