baseus ba07 on debian

do you know how can I make this bluetooth 5.3 dongle work on debian stable? Should I change the kernel? Or just wait a year?

Ok it is almost a year old story. Here is a "bug" report about it: https://bugzilla.kernel.org/show_bug.cgi?id=217870
It looks like we still do not have driver for it.

It is quite interesting (or how to say). It is know for years now, here is a fix from 2022: https://patchwork.kernel.org/project...@holtmann.org/
But it looks like it does not make it work.
Here is another fix from 2024: https://lore.kernel.org/all/20240227...t64@gmail.com/
And it still does not work for me.

What I do not really understand: a lot of well documented standard features are missing from this chip, like in the patch:

Quote:

the HCI_OP_READ_ENC_KEY_SIZE command is skipped during an HCI_EV_ENCRYPT_CHANGE event. This is required for Actions Semiconductor ATS2851 based controllers, which erroneously claim to support it.

two additional patches. The first one is missing from the kernel, but is required to make this device work. I don't know why.
The second one is based on the first one, therefore it is missing too (at least it looks like).

I don't really understand what's going on. It looks like I need to build my own kernel if I want to use this BA07. Despite the fact we have a lot of different patches already available (for a year now) the [latest] kernel still does not contain a working solution.
