我有一个戴尔 Thunderbolt USB-C 底座，但它似乎只在启动时工作。我已插入显示器、键盘和鼠标。
如果我启动时插入雷电，一切都会顺利，但如果我热插拔，显示屏就会闪烁，然后什么都没有。
我在 ubuntu 16.4 上使用内核 4.13.0-41
udevadm monitor看到它：

鼠标和键盘在 中正确显示lsusb，但无法使用。
modprobe thunderbolt不返回任何内容并且不做任何改变。
看来 USB-C 热插拔支持很久以前就从 RHEL 移植到主线内核了 - 所以我认为这不是问题所在，我不知道还有什么原因导致的。有人知道为什么我不能使用这些设备吗，即使它们出现，也只有在热插拔时才会出现？
