Linux 如何知道服务器是否有 USB2 或 USB3

我有一台没有文档的服务器，我计划购买一个 USB3 的 USB 存储设备，现在我想知道该服务器是否有 USB2 或 USB3。

我试过

dmesg | grep usb

我不太明白，但在我看来好像只有 USB1 和 USB2

还有其他方法可以检查吗？

答案1

从您的日志来看，系统似乎有 EHCI USB 控制器。这意味着 USB2。尝试grep对于 XHCI。

我将使用dmidecode -t 2找到主板型号。然后你大概就能在网上找到规格了。

答案2

感谢 Krasi，我发现了 dmidecode 和选项：

dmidecode --类型连接器

所以我有 4 个 USB 3.0 端口
