可能是USB3.0端口不能为您的外部驱动器提供足够的电源，或者控制器不兼容。在这两种情况下，您都可以尝试通过USB集线器连接外部驱动器，USB集线器应该有外部电源，以便在USB总线上提供更多的电源。
当dmesg输出诸如“设备描述符读/8，错误-110”之类的消息时，这通常意味着存在硬件问题。作为华尔丁仪 指出，这组特定的消息有更具体的建议：“也许USB电缆坏了？”
Linux内核通常无法区分不良的USB电缆和其他妨碍传输电源或数据的问题。除了电缆，它一般值得检查连接和确保设备有足够的动力。
你发现用动力轮毂解决了问题，这在提供错误消息时是有意义的。将来看到类似消息的读者将很好地尝试这一点，并考虑其他可能干扰数据或电源的硬件问题(其中一些问题很容易解决)。
