我正在努力将 Netgear AXE3000 Wi-Fi 6 适配器连接到 Ubuntu 22.10 系统。此特定适配器的背景这里。
适配器直接插入主机（Dell 7490）即可工作。但是插入USB 3.0 集线器该适配器不可用ip a。
这是 lsusb 的输出，检测到两个适配器：

当我lsusb -v将适配器插入计算机并再次将适配器插入集线器时，只有两条线不同：
在计算机中：
Bus 002 Device 003: ID 0846:9060 NetGear, Inc. Wireless_Device
Bus 002 Device 002: ID 0846:9060 NetGear, Inc. Wireless_Device
在中心：
Bus 002 Device 006: ID 0846:9060 NetGear, Inc. Wireless_Device
Bus 002 Device 005: ID 0846:9060 NetGear, Inc. Wireless_Device
我尝试sudo dmesg查看当集线器和适配器插入时内核报告了什么。

问题似乎是rejected 1 configuration due to insufficient available bus power。
这是连接了 60W 电源的有源集线器。是否有可用的配置设置来覆盖集线器由总线供电这一明显错误的假设？
答案1
在搜索和研究了 USB 子系统几个小时后，我一无所获。在得出结论：集线器报告自己为总线供电，而实际上它是自供电的之后，我去买了一个新的集线器。我从凡泰克具有类似能力。
一切运行正常。dmesg 中未报告任何错误：
[59222.814154] usb 2-4.1.1: Product: USB3.0 Hub
[59222.814155] usb 2-4.1.1: Manufacturer: VIA Labs, Inc.

[59222.816286] hub 2-4.1.1:1.0: 4 ports detected
我不知道我最初购买的 Sabrent 集线器是否有缺陷，或者设计是否有缺陷。我认为它在任何操作系统上都会失败，而不仅仅是 Linux。不过，我不确定只能通过总线供电的 10 端口集线器有什么用处。
我推荐 Vantec（或使用 VIA Labs 芯片组的类似集线器）
