I am working to attach the Netgear AXE3000 Wi-Fi 6 adapter to a Ubuntu 22.10 system. Background on this particular adapter here.

The adapter works when plugged directly into the host computer (Dell 7490). However when plugged into a USB 3.0 hub the adapter is not available in ip a.

Here's the output of lsusb, with two adapters detected:

lsusb

Here is the output of lsusb -v

When I perform lsusb -v with the adapters plugged into the computer and then again with the adapters plugged into the hub, only two lines are different:

In the computer:

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

In the hub:

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

I tried sudo dmesg to see what the kernel reported when the hub and adapters were plugged in.

The issue seems to be rejected 1 configuration due to insufficient available bus power.

This is a powered hub with a 60W power supply connected. Is there a configuration setting available to override the apparent incorrect assumption that the hub is bus-powered?

  • How many devices are connected to the powered bus? You might have too many devices connected.

  • As linked above, this is a 10-port USB 3 powered hub. The hub is powered with a 60W external power supply. I have 3 devices, two Wi-Fi and one GPS.

  • do you know the required wattage of each wifi device and the GPS? 60W external power supply means the hub's external powered state is 60W total for all the USB devices, if any of them pull more than 60W when combined together there's your error.

  • As shown in the lsusb -v output above, the device reports MaxPower 160mA. I'm using 2 devices. Even if all 10 ports had a 160mA device, that would be 1.6A (*5V = 8W) well below 60W supply. As a test, I plugged one Wi-Fi adapter into the hub - nothing else. I still get the error rejected 1 configuration due to insufficient available bus power

  • I think the issue is with the dmesg: can't connect bus-powered hub to this port. Ubuntu thinks this is a "bus powered hub" when it is externally powered. Is that something I can fix in configuration, or is the hardware defective?

After searching and studying the USB subsystem for hours, I was getting nowhere. After concluding that the hub was reporting itself as bus-powered when it was self-powered, I went and purchased a new hub. I found one from Vantec with similar capabilities.

It worked fine. No errors were reported in dmesg:

[59222.814154] usb 2-4.1.1: Product: USB3.0 Hub
[59222.814155] usb 2-4.1.1: Manufacturer: VIA Labs, Inc.
[59222.814157] usb 2-4.1.1: SerialNumber: 000000000
[59222.816135] hub 2-4.1.1:1.0: USB hub found
[59222.816286] hub 2-4.1.1:1.0: 4 ports detected

I don't know if the Sabrent hub I purchased first is a defective unit, or a defective design. I would expect it would fail on any OS, not just Linux. I'm not sure what use a 10 port hub that could only function as bus-powered would be, though.

I'd recommend Vantec (or similar hubs using the VIA Labs chipset)
