我不确定我是否应该在这里问这个问题，所以如果这是错误的地方，请告诉我，我可以去其他地方发帖。我正在跑步HugeGreenBug 的适用于 Acer c720 的 Ubuntu 14.10使用 coreboot（内核 3.18.7），我正在尝试Inateck HBU3VL3-4 USB 3.0 集线器+千兆以太网适配器无法工作。他们网站上的驱动程序无法编译，但我能够使用答案中的说明使其工作这里。现在来谈谈实际问题。该设备将在 USB 2.0 插槽中工作。

如您所见，它被识别为 USB 2.0 集线器，我可以使用以太网和 USB 端口。但是当我将其插入 USB 3.0 插槽时，USB 端口似乎没有通电，或者供电很弱，以太网无法识别，输出发生变化。
