大家好，我目前正在尝试把Netgear AXE3000 Wi-Fi 6适配器接到Ubuntu 22.10系统上。这个适配器直接插在我的Dell 7490主机上时完全正常，但一旦插到USB 3.0 hub里，用ip a就找不到它了，想请教下有没有解决办法。

设备检测情况 #

先放一下lsusb的输出，能看到两个适配器都被系统检测到了：

直接插主机 vs 插hub的差异对比 #

我分别在适配器直接插主机和插hub时都运行了lsusb -v，发现只有设备编号不一样：

• 直接插主机：

  Bus 002 Device 003: ID 0846:9060 NetGear, Inc. Wireless_Device
  Bus 002 Device 002: ID 0846:9060 NetGear, Inc. Wireless_Device
  

• 插hub后：

  Bus 002 Device 006: ID 0846:9060 NetGear, Inc. Wireless_Device
  Bus 002 Device 005: ID 0846:9060 NetGear, Inc. Wireless_Device
  

内核日志的关键错误 #

我运行了sudo dmesg查看内核输出，找到了导致问题的关键信息：

核心问题就是这两行错误提示：

usb 2-3.1: rejected 1 configuration due to insufficient available bus power
usb 2-3.2: rejected 1 configuration due to insufficient available bus power

但我的这个hub是带60W电源的供电hub，现在系统好像误以为它是总线供电的，想问下有没有什么配置可以强制纠正这个判断，让适配器能正常工作？
