我无法将键盘传递到虚拟机。它与我的主机断开连接，就像它可以工作一样，但事实并非如此。有趣的是，为了以后在主机上重复使用键盘，我必须物理断开并重新连接键盘。
最初，我认为这是 USB 3.0 的问题，但是，我可以通过 USB 3.0 端口安装 USB 3.0 拇指驱动器。此外，我的无线组合键盘和鼠标：Logitech k260 也可以使用。该组合键盘 + 鼠标是 USB 2.0，通过 USB 2.0 集线器连接到 USB 3.0 端口。我的 RAT7 鼠标也可通过 USB 2.0 端口工作。
其他一切都完美地通过。我的 GPU 正在工作，我在游戏中获得了 60 FPS，我的声音可以工作（尽管是以一种迂回的方式），等等。只有这个键盘。
更新：
因此，在插入和拔出一些东西之后，尝试在启动后实时连接键盘等。键盘似乎正在连接到虚拟机。然而，键盘仍然无法使用。键盘USB Composite Device在 Windows 设备管理器中显示为。即使安装驱动程序后，尝试删除并重新安装驱动程序，它仍然无法正常工作。我将尝试启动进入安全模式，看看它是否无法从那里修复。不过，我觉得这可能行不通。尝试重新启动进入安全模式并修复键盘无效。

答案1
好的，所以我找到了一个解决方案，尽管它更像是一种解决方案，而不是一个正确的解决方案。所以据我所知，我仍然无法直接通过键盘。
为了解决这个问题，我所做的就是首先删除我的无线键盘/鼠标直通，然后添加我的好鼠标作为直通。所以我的无线组合适用于我的 Linux 主机，好的键盘也适用于 Linux 主机，只有好的鼠标仅适用于 Windows。
然后我设置了一个显示 Spice 服务器，让 Windows 作为 Linux 中的窗口运行，但是，这里没有显示，只有黑屏（这很好）。现在，我用我的无线组合点击这个窗口，用我的好鼠标控制窗口，我的好键盘的击键也被传递了！
我有点担心这会导致一点延迟，但是，在“脏炸弹”中进行一轮测试后，我感觉鼠标或键盘都没有明显的延迟。所以它看起来工作得很好。我仍然更愿意直接通过硬件，但我不能抱怨。
