DA200 适配器之前出现过问题，即 HDMI/DVI 端口在 Linux 上无法工作（请参阅这里)。然而，4.5 内核更新应该可以解决这个问题。
但是现在，适配器上的 USB 端口停止工作，因此我无法连接鼠标/键盘。在 上lsusb，适配器显示为以下之一：
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
不确定是哪一个，也不确定为什么它会添加 2 个这样的总线设备（不管它们是什么）。
它的 HDMI 和以太网端口似乎可以工作。我正在运行内核4.18.16-041816-generic。我认为它是在我尝试使用新键盘/鼠标（使用适配器上的 USB 插槽）时启动的。它是否可能试图安装一个现在正在干扰其工作的驱动程序？
我想知道是否有人知道我该如何开始排除故障。例如，有没有办法检查插入某些东西时适配器上的哪些端口被“识别”？或者它知道哪些设备已插入？
根据 @chilli555 的建议，我运行tail -f /var/log/syslog，等待几秒钟，然后进入设备 - 使用屏幕的 HDMI、鼠标的 USB-3（不工作）和连接到设备的以太网电缆。顺便说一句，我现在注意到以太网电缆也无法使用。我得到了以下长输出（抱歉）：
