Udev 规则不适用于 fedora 24

Question

当usb 自动插入fedora 24 时，我正在尝试执行脚本。我找到了很多关于如何在旧版本上执行此操作的信息。但是，在 Fedora 25 中它不起作用。这就是我所做的：

我在 /etc/udev/rules.d/ 中创建了一个名为 60-francisco.rules 的文件并包含下一个内容，但它不起作用：

KERNEL=="sdb1",SUBSYSTEM=="block", ENV{ID_MODEL}=="DataTraveler_G3", ATTRS{idVendor}=="0951", ATTRS{idProduct}=="1643", RUN+=" /root/usb_script.sh"

（一切都在一条线上...）

这是 udevadm info --attribute-walk --name=/dev/sdb 命令的结果

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

就像你可以看到文件中的信息很好所以我不知道为什么它不起作用。我已经尝试了所有组合，但没有办法..

拜托，有人可以帮帮我吗？

问候，

如果您将ATTRS{product}=="DataTraveler G3" 替换为ENV{ID_MODEL}=="DataTraveler_G3"，您将不会依赖在应用您的规则之前设置ID_MODEL 变量的其他要触发的规则。由于规则文件是按词法排序的，因此也可以通过重命名规则文件以便稍后排序来解决问题。从您的udevadm 输出来看，ID_MODEL 变量可能已丢失。
