Hi,
I’ve been struggling to use an USB 3.0 Ethernet adapter for that last few days on my PC (running latest stable Manjaro). The adapter is D-Link DUB-1312.
The adapter works perfectly only on USB 2.0 port (not SS). On USB3 port, LED indicators are working (power + 1G speed), but Manjaro doesn’t recognize it at all. lsusb returns the same state, nothing new on dmesg and journalctl (if it’s relevant). ifconfig returns the same data, no new interface.
Please read this: [HowTo] Provide System Information
and press the three dots … below your post and press the to give us more information so we can see what’s really going on.
Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information for us to be able to help you. (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
P.S. If you want to notify me that you did provide this information, please this message and I’ll come back and have another look.
