我正在尝试设置我的 USB 3.0 迷你基座（https://en.j5create.com/products/jud380）。到目前为止，除了 HDMI 端口之外，我可以让所有端口正常工作。
以下是输出lsusb：

我尝试loader.conf按照http://manpages.ubuntu.com/manpages/bionic/man4/umct.4freebsd.html通过添加umct_load="YES"到/boot/efi/loader/loader.conf。在我尝试此步骤之前，该/boot/efi/loader路径不存在，因此我不知道是否正在加载这个新文件。

假设基座内除 HDMI 之外的所有端口均能被检测到，我该如何仅对 HDMI 端口进行故障排除？
