每當插入我的 SteelSeries Xai 滑鼠時，都會有 15 秒的延遲，直到滑鼠被正確識別並開始工作。這在啟動時特別麻煩，udev 等待 15 秒鐘什麼也不做。
以下是我在dmesg開機時找到的相關資訊：

正如您所看到的，在 15 秒的時間裡，udev什麼也沒做。
但是，當我拔下插頭然後重新插入時，過程有點不同：
[22660.547752] usb 6-1: new full-speed USB device number 3 using uhci_hcd
[22665.718517] input: Ruling Technologies Sdn. Bhd. SteelSeries Gaming Device as /devices/pci0000:00/0000:00:1d.0/usb6/6-1/6-1:1.0/input/input19

現在它似乎以 5 秒的間隔識別滑鼠的各個部分。
問題可能出在滑鼠上。我過去在 Linux 上遇到過問題，所以我不會放棄它。不過，我感興趣的是至少一個解決方法，這樣我的啟動過程就不會花那麼長時間（DE 大約需要 45 秒，所以 15 秒什麼都沒有很多）。如果每次插入電源時我仍然需要等待 15 秒，那也沒關係。滑鼠運作正常，不會自行重新連線。
那麼：有沒有辦法加快設備偵測速度，即使是手動檢測？
或者：有什麼我可以做的，udev這樣它就不會在啟動時等待這個特定設備響應？
