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?
