Windows下Docker容器无法访问蓝牙适配器的技术求助

理论上已有成熟解决方案，但Windows系统下集成蓝牙适配器并不像旧帖描述的那样简单，推测是技术栈更新引发了新问题。尝试过多数基于Linux主机的方案，但WSL环境下的适配问题始终未解决。

环境栈 #

• WSL版本：2.3.14.0（未使用最新2.3.17，因蓝牙适配器需Kernel 6.6驱动，自定义内核会导致Docker Desktop异常）
• Kernel版本：6.6.36.3-1
• Docker Desktop：4.33.1
• Docker：27.1.1
• USBIPD：4.3.0

已执行步骤与验证结果 #

1. WSL2中验证蓝牙功能正常：
   配置USBIPD后，WSL可正常识别蓝牙适配器：

# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 10d7:b012 Actions general adapter
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

$ bluetoothctl
Agent registered
[CHG] Controller F4:4E:FC:8E:1A:30 Pairable: yes

$ hciconfig hc0
hci0:   Type: Primary  Bus: USB
        BD Address: F4:4E:FC:8E:1A:30  ACL MTU: 679:6  SCO MTU: 240:20
        UP RUNNING
        RX bytes:1825 acl:0 sco:0 events:110 errors:0
        TX bytes:4419 acl:0 sco:0 commands:97 errors:0

2. 准备Docker镜像与容器：
   2.1 Dockerfile：

FROM ubuntu:latest

RUN apt-get update

RUN apt-get install -y bluez bluetooth usbutils

COPY docker_entrypoint.sh /usr/src/app/docker_entrypoint.sh

ENTRYPOINT sh /usr/src/app/docker_entrypoint.sh

2.2 docker_entrypoint.sh：

#!/bin/bash

service dbus start
bluetoothd &
/bin/bash

2.3 停止WSL主机蓝牙服务并验证：

$ sudo service bluetooth stop

验证服务已停止：

$ bluetoothctl
Waiting to connect to bluetoothd...

$ sudo hcitool lescan
Could not open device: No such device

2.4 构建镜像并启动容器：

docker build -t myimage .
docker run --rm --net=host --privileged -it myimage

容器内遇到的问题 #

• 可识别蓝牙设备：

# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 10d7:b012 Actions general adapter
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

• bluetoothd无法正常运行：

# service bluetooth status
 * bluetooth is not running

# bluetoothd -n
bluetoothd[65]: Bluetooth daemon 5.72
bluetoothd[65]: src/adapter.c:adapter_init() Failed to access management interface
bluetoothd[65]: src/main.c:main() Adapter handling initialization failed

# hciconfig hc0
Can't open HCI socket.: Address family not supported by protocol

• 蓝牙模块已加载：

# lsmod | grep bluetooth
bluetooth             741376  6 btrtl,btintel,btbcm,bnep,btusb
ecdh_generic           12288  1 bluetooth

• dmesg日志：

# dmesg | grep Bluetooth
[   75.485496] Bluetooth: Core ver 2.22
[   75.485527] Bluetooth: HCI device and connection manager initialized
[   75.485532] Bluetooth: HCI socket layer initialized
[   75.485534] Bluetooth: L2CAP socket layer initialized
[   75.485538] Bluetooth: SCO socket layer initialized
[ 3675.898623] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[ 3675.898630] Bluetooth: BNEP socket layer initialized
[ 3695.249669] Bluetooth: hci0: HCI Read Default Erroneous Data Reporting command is advertised, but not supported.
[ 3695.249672] Bluetooth: hci0: HCI Read Transmit Power Level command is advertised, but not supported.
[ 3695.249674] Bluetooth: hci0: HCI LE Set Random Private Address Timeout command is advertised, but not supported.
[ 3695.364291] Bluetooth: MGMT ver 1.22

另外尝试过共享系统总线套接字启动容器（不使用--net=host参数）：

$ docker run --rm -it -v /var/run/dbus/:/run/dbus/:z --privileged myimage
 * Removing stale PID file /var/run/dbus/pid.
 * Starting system message bus dbus 

结果与上述问题完全一致。

硬件层面无异常，但容器内始终无法正常使用蓝牙，恳请提供解决方案。
