我在 Ubuntu 11.10 中使用 AOpen PS/2 机械鼠标Staples USB 转 PS/2 适配器使用我的 Intel DP67DE 主板。由于鼠标比光学鼠标高度低，因此我的手握起来更舒服。有时鼠标光标会冻结，我经常必须将其从 USB 端口拔下，然后重新插入另一个 USB 端口才能解冻。所有 USB 端口都会发生这种情况。我已经使用适配器几个星期了，最近这种情况似乎更频繁地发生。可能发生了什么，有什么可以解决此问题的方法吗？

答案1
嗯，听起来连接不太好，而且经常断线。
这里有几种可能性。
首先，鼠标本身因老化而出现故障 - 可能是某个地方的电容器出现故障，或者其他原因。将其打开（并花点时间清洁内部），然后目视检查是否有膨胀的盖子 - 如果有，请更换它们
我还听说过一些问题，一些较旧的设备需要的电流超过 USB 所能提供的电流，尽管一些质量更好的适配器可以解决这个问题。
Geekhack 还指出，有些适配器在ps/2 适配器指南- 获得更好的 PS/2 适配器甚至是不同的适配器。
