Where to check for future bluetooth kernel support

I am unable to enable Bluetooth on my system. I am running kernel version: 5.19.0-38-generic on Ubuntu 22.04LTS; with the following info for my bluetooth/wifi module: link(USB 0489:e069). It seems to indicate this is not supported by Linux at the time of writing. I am wondering how to track if there is any sort of progress being made to include support for this device in the 6.2 kernel.

The 6.2 kernel is currently used by Ubuntu *lunar* which will be 23.04 when released; after release that kernel will become the *edge* kernel of 22.04, which after testing will become the HWE kernel stack prior to the release of Ubuntu 22.04.3 LTS (*I was going to add jammy release schedule, but no date is set yet for 22.04.3, but even then it's available some time before then via install of the -edge kernel*)

Please edit to include results from terminal for `sudo dmesg | egrep -i 'blue|firm'; lspci -nnk | grep -iA3 net`

@Jeremy31 I have updated to include output from the command you posted.

You can test this to see if it makes the Bluetooth work. Secure Boot needs to be disabled, check mokutil --sb

sudo apt install git dkms
git clone https://github.com/jeremyb31/bluetooth-5.19.git
cd bluetooth-5.19
make -j4 -C /lib/modules/$(uname -r)/build M=$(pwd) modules
sudo mv /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.bak
sudo mv btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/btusb.ko

Reboot, if it works file a Ubuntu bug against package linux and include results from terminal for sudo cat /sys/kernel/debug/usb/devices | awk '/e069/' RS=

I can confirm that this chipset works with Ubuntu 23.04 with its default 6.2 kernel.

I had the same error when I installed Ubuntu 22.04 LTS on a new workstation. The computer has the same chipset as that reported by cogle in their question:

Network controller [0280]: MEDIATEK Corp. Device [14c3:0616]
Subsystem: Foxconn International, Inc. Device [105b:e0cd].

My workstation reported the same error:

Bluetooth: hci0: Opcode 0x c03 failed: -110

I have since upgraded the system to Ubuntu 23.04 and Bluetooth now works.

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.
