Hello everyone, I have two arduino uno's,, before all are working fine,, but just today i descovered that my blue one cannot be detected any more in my Pc , particularly in the Device manager,, i dose not even make the insertion sound anymore, ,, nothing just happens upon inserting,,, but my other one is working fine with thesame USB cable,, what possibly might be wrong?, im hoping someone could shed me some light on this problem,,, tnx in advance

i think the problem is in the USB ic connection parts, because the atmega328p is ok, coz i tested with the blink code on my working unit, then transfer the it to problematic one,,, the blink still works there, but i cant use the USB anymore for edits and compile,,, what a sad day
