Hi everybody,
When I plug my Uno to my PC, it recognizes the UNO with no problem.
Then I unplug it and plug again and PC does not recognize it anymore. No serial port.. Nothing..
If I wait for 1-2 hours and connect again, it works.. Then I unplugged and plug.. again.. does not work...
During all these, Uno runs the program when it has power (with USB or with power socket) there is no problem with this..
Did you see something like this before? Any idea?
