我在 MSI CX61 2QC 笔记本电脑上运行 Ubuntu 22.04。我在蓝牙方面遇到了一些问题,我怀疑这些问题可能是由过时的驱动程序引起的,甚至是由于 Linux 上没有此设备的驱动程序。
为了检查我的笔记本电脑有哪种蓝牙设备,我已执行以下操作:
dmesg | grep -i blue
[ 1.447635] usb 1-1.3: Product: RT Bluetooth Radio
[ 2.570559] Bluetooth: Core ver 2.22

[ 2.643783] Bluetooth: hci0: RTL: assuming no firmware upload needed
蓝牙似乎是通过 USB 连接的,因此我执行以下操作:
lsusb
[...]
Bus 001 Device 004: ID 13d3:3394 IMC Networks Bluetooth
[...]
我该如何安装该驱动程序?

按照如下所述禁用 Windows 快速启动后,我知道会看到以下内容dmesg

答案1
这是 Realtek 设备。更准确地说,它是一个芯片。您可以从带有内核源代码Realtek 8723AE
的日志消息中找到这一点RTL
btusb.c
{ USB_DEVICE(0x13d3, 0x3394), .driver_info = BTUSB_REALTEK },
这些消息表明 Linux 内核对该 IC 的支持不佳:
[ 2.643774] Bluetooth: hci0: RTL: examining hci_ver=06 hci_rev=0e3d lmp_ver=06 lmp_subver=a5b1
[ 2.643780] Bluetooth: hci0: RTL: unknown IC info, lmp subver a5b1, hci rev 0e3d, hci ver 0006
[ 2.643783] Bluetooth: hci0: RTL: assuming no firmware upload needed
可能需要一些固件。
我的建议是:
尝试安装最新的主线内核并检查其运行情况。可能已添加对此设备的支持。
如果第 1 条没有帮助,请通过运行向 Launchpad 报告错误

如果安装是与 Windows 双启动,请禁用 Windows 快速启动功能并检查它是否有帮助。
