我在 Ubuntu 16.04 上使用 FREEWAY TECHNOLOGY 的空中鼠标时遇到了这个奇怪的问题。
如果我使用 USB 集线器连接 USB 密钥，设备可以正常工作，如果我尝试将其直接连接到计算机 USB 端口，则会收到一些错误并且设备无法工作。

我对其他 USB 设备也有类似的体验。这些设备与计算机中的系统（硬件和/或软件）不太兼容，但集线器可以提供一个接口，可与 USB 设备和计算机中的 USB 系统配合使用。
我的解决方案（也许你会称之为解决方法）是使用集线器并感到高兴。
如果它是一个非常新的设备，并且是一个软件问题，也许更新或未来版本的 Ubuntu 将使其在没有集线器的情况下工作。
你可以试试居住, '尝试 Ubuntu', 从 USB 驱动器或 DVD 磁盘启动Ubuntu 17.10.1和Ubuntu Bionic即将（2018 年 4 月）作为 Ubuntu 18.04 LTS 发布。
USB 闪存盘可能需要也可能不需要计算机从其启动的集线器 ;-)
