Bluetooth boot error

I'm getting this error on boot:

Bluetooth: hci0: Opcode 0x c03 failed: -16

When I try to turn on the bluetooth, it just stays like this and nothing happens:

My ubuntu version is 22.04.2.

Edit: I found a partial solution: https://ubuntuforums.org/showthread.php?t=2486644, the boot error isn't showing up anymore but I still can't turn on the bluetooth.

Please edit to include results from terminal for `lsusb; sudo dmesg | egrep-i 'blue|firm'`

Can you try `bluetoothctl` and then do `power on`

See if anything changes after `sudo modprobe btusb`

What result for `mokutil --sb` if secure boot is enabled the fixed btusb module won't load

The fix won't work with Secure Boot enabled unless you use mokutil and that might be more work than it is worth

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
