I have an external USB network adapter (Edimax) which is not recognized after I plug into my Ubuntu 18.04 laptop. First of all I ask ubuntu to list me all USB devices by
lsusbit shows all connected devices (and even more, this laptop has only two USB ports but lsusb prints 5 records why is that?) beside that network adapter. When I unplug it and plug again
dmesg also doesn't metion it at all.
The adapter itself works properly on other laptop with windows, the usb port is also OK since other devices work OK. So what is the problem?
PS: I also have to add that at work I have the exact same adapter (in terms of model and producer) and that one works OK.
