我正在MSI CX61 2QC笔记本上运行Ubuntu22.04。我在蓝牙上遇到了一些问题,我怀疑它们可能是由过时的驱动程序引起的,甚至可能是因为Linux设备上没有驱动程序。
为了检查我的笔记本电脑有哪种蓝牙设备,我做了如下工作:
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连接起来的,所以我做了:
lsusb
[...]
Bus 001 Device 004: ID 13d3:3394 IMC Networks Bluetooth
[...]
我该如何安装驱动程序呢?
在禁用Windows (如下面所解释的)之后,我知道在dmesg
中可以看到以下内容:
[ 1.727956] usb 1-1.3: Product: RT Bluetooth Radio

这是Realtek设备。更精确地说,它是一个Realtek 8723AE
芯片。您可以从使用RTL
和内核源代码btusb.c
的日志消息中找到这一点。
{ USB_DEVICE(0x13d3, 0x3394), .driver_info = BTUSB_REALTEK },
这些消息表明,Linux内核并不很好地支持IC:
[ 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
也许需要一些固件。
我的建议是:
如果安装是Windows的双引导,请禁用Windows快速启动功能,并检查它是否有帮助。
