Please use code tags, https://bbs.archlinux.org/help.php#bbcode and don't post random greps.
Post the entire dmesg/system journal and also lspci & lsusb outputs.

And more information if i run "power on" in bluetoothctl it outputs

[bluetooth]# power on
No default controller available

The dmesg only starts 3.6 seconds in and the only visible BT device is this dongle

0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

- is that correct and the concerned one?
It's added but not even decoded, there's no mention of driver or firmware and after ~18 minutes it disappears and in turn you get bluetooth errors. Then it's a flaky on off relation.

Searching the usb id gets you a lot of "doesn't work" hits and also https://bbs.archlinux.org/viewtopic.php?id=257372
The thread suggests that it was fixed w/ one of the recent kernels.
Since you conveniently stripped the kernel info from dmesg there's no way to tell whether you can expect more, but linux-hardware.org seems to only have it working w/ recent kernels.

I am using the latest kernel.

uname -a                                                                        
Linux username 5.11.6-arch1-1 #1 SMP PREEMPT Thu, 11 Mar 2021 13:48:23 +0000 x86_64 GNU/Linux

And this adapter is not new, it worked for several months, and then for some reason stopped working.

So, what changed?
Does it still work w/ the lts kernel?

Please dig up an old journal from when it still worked, so we can look at the differences.

Here is a system log from a week ago:

Linux 5.11.6-arch1-1

so there wasn't a kernel update.

From what I can see you crng is late and it's done before the BT in the "good" boot and afterwards in the "bad" one…

I installed haveged and it still doesn't work

seth · 2021-03-14 13:45:30

Did you also enable it?
Updated journal?

Edit: also try the dongle on a different system/software stack (live distro) to rule out that the HW is simply fried.

I just tried using this dongle in Tails Linux and it didn't work there I think it just got fried

And the last question how to close this topic

seth · 2021-03-14 14:13:52

You can mark resolved threads by editing your initial posts subject (link in the lower right corner)
Please don't use "closed" but eg. "hardware issue" or so.

SATAx15 · 2021-03-14 14:15:34

Just add [SOLVED] in first message?
