So I checked the log and I have no message at all when I plug any of my 3 pendrive in any of my 3 ports.
I suppose I did it good because if I disconnect my wifi for example the log is writing it normal.
What is also weird is that pendrives are not even doing the light signal, one of them does it very quickly, the others not at all, but anyway none of them is doing the classical blinking.
So I really don't have any idea, everything else seems to work normal. It looks like they are desactivated or something, but as far as I know, usb port are not like wifi or webcam in laptops, they cannot be disabled by inadvertance. Or am I wrong?
Haha, thank you I already spent some time on this this morning, and as I said I could upgrade finally
