Problematic Bluetooth USB dongle gets recognized by lsusb but doesn't work

[MandSpades]

So, I've been trying to troubleshoot my DualShock 4 here, and eventually came to the potential solution of trying to see if it works better on Bluetooth. So I bought myself a BT dongle. Said dongle gets recognized by lsusb, but Blueman doesn't even want to start. I'm gonna show you now several commands and how it shows up on all of them. Can someone help me with troubleshooting and solving this issue?

You may have to try newer kernels to see if the kernel developers found a way to get it to work.

[MandSpades]

What new kernels? Would trying 6.1 OEM be a good idea? I'm already on kernel 6.0 right now, so I have to wonder if a 6.1 OEM kernel would suffice. Also, is the 6.1 OEM kernel even the same as the 6.1 LTS kernel?

[SMG]

Also, is the 6.1 OEM kernel even the same as the 6.1 LTS kernel?

No, there are some differences. The 6.1 OEM kernel is an OEM Kernel maintained by Canonical (Ubuntu).

The 6.1 LTS kernel is a mainline kernel.

The 6.1 LTS kernel is a mainline kernel.

I mean, like, practical differences. Next version of Linux Mint is probably gonna be changing to the mainline 6.1 kernel. What kernel do you recommend me to try? Also, I forgot the command to install ç-ç

[SMG]

I mean, like, practical differences.

There are "practical" differences between OEM kernels and "regular" Canonical kernels. Additionally, Canonical kernels are optimized so Ubuntu works well while mainline kernels are not optimized for any particular distribution.

Next version of Linux Mint is probably gonna be changing to the mainline 6.1 kernel.

No, it will not. The edition of Linux Mint based on Ubuntu does not use mainline kernels at all.

All Linux Mint 21 versions are based on the 5.15 kernel which is the LTS kernel. As HWE kernels (newer kernels for newer hardware) are released by Canonical, they become available for use in Linux Mint. I expect there will be an Edge version ISO for LM21.2 with one of these newer kernels, but do not know for sure that 6.2 will be used (but it is my guess that it will be--that is just my guess).

What kernel do you recommend me to try? Also, I forgot the command to install ç-ç

I don't have any recommendations for your bluetooth issue.

[JeremyB]

If you install the mainline program from github you should be able to install kernel 6.3.5- https://github.com/bkw777/mainline
The Cambridge Silicon Radio Bluetooth dongles have been a problem in Linux since I have been using it because they all use the same USB ID, sometimes the Linux kernel devs can get them working

Known working Bluetooth USB dongles are Iogear GBU-521 and Edimax BT-8500

Is it not better for me to install 6.3 from Ubuntu's OEM kernels, or do they not have this version yet? I feel like with Canonical's support it would be much safer.

[SMG]

If there is not a linux-oem-22.04d available yet in Synaptic, then 6.1-oem is the newest.

[MandSpades]

It goes up to 22.04c
I assume that's not enough?

[SMG]

It goes up to 22.04c

That is the 6.1-oem kernel. I do not know when the next one might be released.

[MandSpades]

The problem is mostly solved! It doesn't detect my DualShock4 for some weird reason but at least that one now works over USB.

[MandSpades]

Additional testing, in case someone were already writing a response:

I tested it with a JBL bluetooth earphone and it does detect it. Seems like only the DS4 doesn't get detected yet...

[MandSpades]

Well, the BT dongle works, though the DS4 doesn't work with it.

So quick question: when is the 6.2 OEM kernel expected to come out again? I remember something about July.

The 6.2 HWE kernel (the replacement for the 5.19 kernel) should be coming available before 5.19 goes end of life in August. I do not know the exact timing.
