I just received my first Arduino board which is essentially a Leonardo (ATmega32U4) customized to include a NFC reader (PN532).
When I plug it in, the PWR LED comes on steady, the D13 LED flashes a few times, and then the STA LED blinks once and only the PWR LED is left on. I can upload a basic sketch to the correct Serial Port, but the Serial Monitor is always empty.
I have noticed that, when uploading the script, the RX/TX LEDs stay off (which I thought was a sign of uploading/downloading data). I figured this was the root of my issue so I tried to look into it further. Running
lsusb does not find the device and
dmesg does not show any information when (un)plugging the device.
I also tried on a Windows install, but couldn’t install the Leonardo drivers since Device Manager wouldn’t register any unknown USB/Arduino devices.
Do you think my board is dead on arrival or am I doing something wrong?
