我使用的是 20.04 版,希望能让工作站正常工作。我使用带电的 4 端口 USB 集线器,在 Windows 上用它来为 USB 转以太网适配器、连接到无线耳机 (Plantronics) 的 USB 适配器和 USB 网络摄像头 (无名称) 供电。
插入后,网络摄像头或耳机会完全停止工作。只有拔掉其中一个后我才能再次收到响应。网络摄像头仍被识别为已插入,只是不再有反应。耳机也是一样。
将它们插入单独的 USB 端口(一个在集线器中,一个直接在笔记本电脑中)似乎可以解决这个问题。
能否解释一下为什么 Hub 在这种特定情况下会停止运行?另一款无线耳机 (SteelSeries Arctis) 确实可以通过同一个集线器与网络摄像头一起工作,没有任何问题,似乎是这个特定设备导致了问题。
以下 lsusb 输出导致问题
