有些事非常Ubuntu 上的 USB 支持有问题。因此，我的主板上有 2 个 USB 3.0 端口，还有 4 个 USB 2.0 端口，前面板上还有 2 个 USB 端口。USB 3.0 无法工作和运行lsusb，以下是发生的情况：

这到底是怎么回事，我刚刚从 Windows 切换过来，开始担心驱动程序兼容性。
也许这是 BIOS 中的问题，但我不知道。注意：我不知道是否相关，但它通过 EFI 启动（我希望这是一件好事）。
评论：之前在计算机上运行的 ubuntu 是 13.04 或 12.10，当时一切似乎都很正常。
我已尝试插入我的游戏手柄、键盘和鼠标。
这些端口似乎有电，例如，我可以给我的手机充电。
