Udev 需要 15 秒来检测鼠标

每当插入我的 SteelSeries Xai 鼠标时，都会有 15 秒的延迟，直到鼠标被正确识别并开始工作。这在启动时特别麻烦，udev 等待 15 秒什么也不做。

以下是我在dmesg开机时找到的相关信息：

[    1.238572] hidraw: raw HID events driver (C) Jiri Kosina

正如您所看到的，在 15 秒的时间里，udev什么也没做。

但是，当我拔下插头然后重新插入时，过程有点不同：

[22660.547752] usb 6-1: new full-speed USB device number 3 using uhci_hcd

现在它似乎以 5 秒的间隔识别鼠标的各个部分。

问题可能出在鼠标上。我过去在 Linux 上遇到过问题，所以我不会放弃它。不过，我感兴趣的是至少一个解决方法，这样我的启动过程就不会花那么长时间（DE 大约需要 45 秒，所以 15 秒什么都没有很多）。如果每次插入电源时我仍然需要等待 15 秒，那也没关系。鼠标工作正常，不会自行重新连接。

那么：有没有办法加快设备检测速度，即使是手动检测？

或者：有什么我可以做的，udev这样它就不会在启动时等待这个特定设备响应？
