If it were a driver problem, it should at least show up as an unknown device.My main problem is that Arduino Micro does not appear ANYWHERE in the device manager.
So the 32U4 processor is running the bootloader. Since it also implements the USB communication, it should be visible as a device. Try a different cable and/or USB port.the light is pulsing at first and then flashing 3 blinks in a row and then a pause. blink-blink-blink-largedelay-blink-blink-blink
