如果将加密狗直接插入笔记本电脑,光标只会稍微摆动,或者有时会响应右键单击。
一些规格:
- 带有 USB 加密狗的通用(中国)无线鼠标。
- Dell Vostro 5560 笔记本电脑,运行 ubuntu-14.04.3-desktop-amd64。
我尝试过的事情:
- 将加密狗插入笔记本电脑中所有可用的 usb3.0 插槽(没有成功)
- 在另一台机器上测试了鼠标(戴尔 Inspiron,运行 peppermint linux 32 位)(鼠标工作正常)
- 使用新充电的电池。
我曾经能够直接使用加密狗让它工作。但是当我连接 USB 记忆棒时,光标的响应逐渐降低,直到完全停止工作。我不记得我是如何让它工作的 - 我浏览了很多论坛帖子,现在我无法重现它。
我希望能够使用鼠标,而不需要笔记本电脑上悬挂的 USB 4 端口扩展集线器。
这是lsusb
将加密狗连接到集线器后,鼠标工作正常的情况:

这是dmesg
将加密狗从集线器上拆下并直接连接到笔记本电脑后,光标对鼠标移动没有反应的情况:

我可以从终端复制粘贴,但我无法解释输出。
编辑:4 端口 USB 扩展上有 USB2.0 标记。如果这很重要的话,鼠标很可能也是 USB2.0。
答案1
解决方案很简单,而且说实话,现在这种解决方案已经不那么常见了。不幸的是,这不是一个容易修复的错误,但很容易告诉你为什么会发生这种情况。USB 2.0 的设计只接收来自其中设备的特定数量和类型的信息,而 USB 3.0 的设计则接收几乎所有的信息。看来你拥有的扩展将 2.0 变成了 3.0。所以基本上,问题在于你的笔记本电脑 USB 2.0,你的鼠标不支持它。希望这对你有帮助!
答案2
它是带有独立电源的集线器吗?一些板载 USB 端口不会为 USB 连接器中的电源引脚提供非常高的电压。可能是您的笔记本电脑没有为适配器提供足够的电压来工作,而集线器提供了更多的电力
