Kanex Thunderbolt 2 高速基座

Question 1

我有一个 OWC thunderbolt 底座，通过 thunderbolt 2 接口连接到我的 dell precision m3800（与您的大致相同）。我刚插入它，它就工作了。

Thunderbolt 是热插拔 pci，它已在 Linux 内核中存在了一段时间（我认为是 2.6），因为它被一些大型存储系统使用，但是通过 usbc 端口访问它是新的。

这是我的 lspci 与 dock

如果您的内核有相应的驱动程序，它将启用 usb c 端口，如果是这样，它将出现在此命令的输出中

lspci -d ::0c03 -k

尝试较新的内核，直到找到可以启用它的内核，英特尔芯片组应该在上游内核中得到完全支持，但似乎还没有在 ubuntu 内核中得到支持。

您的日志中应该有与尝试启用端口相关的条目，请将它们发布在此处。

更新：

理论上您应该能够运行以下命令来重新扫描 pci 总线，这可能有助于唤醒您的基座。

echo "1" | sudo tee /sys/bus/pci/rescan > /dev/null
