我刚刚安装了 Xubuntu 14.04。除了外接 USB 鼠标外，其他一切都运行正常。
这是我正在尝试使用的鼠标。制造商在其数据表中说它应该可以在 Linux 上运行。
当我运行时lsusb鼠标不存在：
jose@jose-laptop:~$ lsusb

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

然后尝试弄清楚发生了什么：

有什么线索吗？
更新：
PC 是华硕笔记本电脑，全新安装 Xubuntu 14.04
我在 BIOS 中启用了 USB 传统支持，现在当我拔下鼠标并再次插入时，它会“随机”工作。有时它可以工作，有时则不行。如果我发现任何其他线索，我会在这里写下来。
答案1
尽管 minicute 表示它支持 Linux，但并不意味着该设备的驱动程序会自动加载。您是否尝试过在软件中心寻找 minicute 鼠标的其他驱动程序？某些第三方专有驱动程序必须“手动”下载和安装。不过，我觉得这很奇怪，因为该鼠标看起来和其他鼠标一样......只是在“侧面”。
答案2
该错误device descriptor read/all, error 2表示与 USB 总线上的设备通信时出现不可恢复的问题。这可能由多种原因造成，主要在电气层面：电缆断裂、电压不良、短路、USB 集线器损坏……
作为第一次测试，您应该尝试使用其他 USB 端口！如果中间有集线器，请将其移除并直接连接鼠标！确保所有电缆和连接器都正常！
答案3
两天后，我终于能让鼠标正常工作了。我所要做的就是在笔记本电脑 BIOS 中启用 USB 传统支持并禁用 xHCI 支持。
