udevadm/persistent USB 名称无效（权限错误）
udevadm/persistent USB names not working (permission error)
我有 2 个相同的蓝牙接收器连接到一个 Raspberry Pi
我需要监控房间不同位置的蓝牙信号。
不幸的是，这两个设备具有相同的 idVendor 和 idProduct 所以我
已经求助于使用 ATTR{serial} 希望 udev 可以
区分两者。
问题是在我创建了 udev 规则（使用新的 SYMLINK）之后，
只有 1 个蓝牙接收器显示正确名称的 DEVLINK
我在规则中提供了。另一个蓝牙接收器的DEVLINK名称是
从未显示。我尝试了很多事情：重新启动，重新加载 udev
规则，重新启动 udevadm。控制台提供以下错误
在 dm 测试中时（下面提供了完整的输出——我认为
根据此输出的后半部分，可能是权限问题？）：
udev_event_execute_rules: no node name set, will use kernel supplied

如果有帮助，这是我为创建规则所做的
执行测试：
首先，我 运行 udevadm info 来识别不同的属性
2 个接收器。
1 台设备上的 idVendor、serial 和 idProduct 如下：
ATTR{idVendor}=="0a5c"
ATTR{serial}=="0002723FAE6C"
ATTR{idProduct}=="21e8"
在另一台设备上...
ATTR{idVendor}=="0a5c"
ATTR{serial}=="5CF37067320A"
ATTR{idProduct}=="21e8"
我创建了一个名为“00-my-usb-device.rules”的新规则文件，看起来
像下面这样：
SUBSYSTEM=="usb", ATTR{idVendor}=="0a5c",
ATTRS{serial}=="5CF37067320A", SYMLINK+="driverBT"
然后我创建了一个名为“01-my-usb-device.rules”的单独规则文件
（最初我在 1 个文件中有两个规则，但想尝试所有
可能性。该文件如下所示：
SUBSYSTEM=="USB", ATTR{serial}=="0002723FAE6C",
ATTR{idVendor}=="0a5c", SYMLINK+="rearBT"
运行 第一个端口上的 devadm 序列号为“5CF37067320A”（也
是我设定的第一条规则）：

如果有帮助，这是我为创建规则所做的 执行测试：
首先，我 运行 udevadm info 来识别不同的属性 2 个接收器。 1 台设备上的 idVendor、serial 和 idProduct 如下：
ATTR{idVendor}=="0a5c"
ATTR{serial}=="0002723FAE6C"
ATTR{idProduct}=="21e8"
在另一台设备上...
ATTR{idVendor}=="0a5c"
ATTR{serial}=="5CF37067320A"
ATTR{idProduct}=="21e8"
我创建了一个名为“00-my-usb-device.rules”的新规则文件，看起来 像下面这样：
SUBSYSTEM=="usb", ATTR{idVendor}=="0a5c",
ATTRS{serial}=="5CF37067320A", SYMLINK+="driverBT"
然后我创建了一个名为“01-my-usb-device.rules”的单独规则文件 （最初我在 1 个文件中有两个规则，但想尝试所有 可能性。该文件如下所示：
SUBSYSTEM=="USB", ATTR{serial}=="0002723FAE6C",

需要内核。 2 个 BT 适配器连接到 4 端口集线器。一旦我在这 2 个规则中的每一个中指定了内核，一切都正常。
产品和序列号也用于区分这两个设备（产品可能不是必需的，因为它与其他 BT 设备匹配，但序列号肯定是必需的）。
