在哪里检查未来的蓝牙内核支持

我无法在系统上启用蓝牙。我5.19.0-38-generic在 Ubuntu 22.04LTS 上运行内核版本：；我的蓝牙/wifi 模块的信息如下：链接(USB 0489:e069)。似乎表明在撰写本文时 Linux 不支持此功能。我想知道如何跟踪在 6.2 内核中是否取得了任何进展以包含对此设备的支持。

其他所需信息：

您可以测试一下，看看蓝牙是否能正常工作。需要禁用安全启动，请检查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

重启，如果成功，请针对 Linux 软件包提交 Ubuntu 错误报告，并包含终端结果sudo cat /sys/kernel/debug/usb/devices | awk '/e069/' RS=

我可以确认该芯片组可与带有默认 6.2 内核的 Ubuntu 23.04 兼容。

当我在新工作站上安装 Ubuntu 22.04 LTS 时，我遇到了同样的错误。该计算机的芯片组与 cogle 在其问题中报告的芯片组相同：

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

我的工作站报告了同样的错误：

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

我已将系统升级到 Ubuntu 23.04，蓝牙现在可以正常工作。
