Im using an arduino Mega 2560. For some reason its not showing up in the COM and LPT ports when I connected it to my pc. For a while it was being shown as an unknown USB device, so I tried to install the driver again. But it didint help and after a while it doesnt show up even in the unknown USB device when I connect it.
I must mention here that the atmega 16 on the board heats up when I connect it to the pc. I dont think it happened before, but this might be the cause of the problem.
Is there anyway I can fix this problem
