A USB3 to RJ45 adapter worked fine for many months on my computer’s USB3 port. Several weeks ago it was no longer recognized on the USB3 port but only recognized on the USB2 ports. The USB3 port is working normally: I have a wireless mouse connected to that port. Here is the result of the dmesg command. Any suggestion?

Hi,

The wiring for usb 2 & 3 is different. So either the port or the device has developed a fault. I would suggest booting a live ISO and connect the USB3 to RJ45 to USB3, if the live ISO can see the device; then its not a hardware fault and it can be investigated further on your current install. If the same issue occurs on the live ISO, I would try a different USB3 device in the USB3 port, to confirm whether its the port or the rj45 adaptor.

Thanks Tom.
