我一直有这个问题，但相关答案都无法解决我的问题。我遇到的这个systemd-udevd实例的资源消耗不断增加，直到笔记本电脑死机。
该问题似乎与具有以下 PCI ID 的 HP 设备有关03f0:0c51，但我无法确定是哪种设备这是.dmesg一遍又一遍地被下列数据轰炸：
$ dmesg

udevadm还显示了不断添加和删除的设备：

奇怪的是，该设备/sys/bus/usb/devices/1-2似乎不存在，因为命令udevadm info --query=all /sys/bus/usb/devices/1-2只是返回一个错误。lsusb情况并没有好转，并且该设备只是不时地出现在结果中，但没有提供任何实际信息：

基本上是一遍又一遍地重复同样的信息。
我尝试添加以下规则：
SUBSYSTEM="usb", ATTR{idVendor}=="03f0", ATTR{idProduct}=="0c51", OPTIONS+="ignore_device", OPTIONS+="last_rule"
SUBSYSTEM="usb", ATTR{idVendor}=="03f0", ATTR{idProduct}=="0c51", ATTR{authorized}="0"
但它们似乎也不起作用。知道我下一步该怎么做吗？
答案1
我在 HP 笔记本电脑上遇到了同样的问题，我的机器 idVendor 03f0 和 idProduct 0c51 是无线广域网（WWAN）：https://support.hp.com/nz-en/document/c04221330
我可以在以下位置禁用它：BIOS/UEFI -> 高级 -> 内置设备选项 -> 移动网络设备 (WWAN)
此后，dmesg 垃圾邮件停止，其他 USB 设备开始正常工作（以前我必须在启动 HP 笔记本电脑之前插入 USB 设备）。
