Just got an Arduino Uno. Out of the box, I've plugged it into my Macbook Pro and the expected "new network interface" dialog does not pop up. As a result, I can't select the serial interface in Arduino application that is needed to upload code.
I see this in system information
ATmega16u2 DFU: Product ID: 0x2fef Vendor ID: 0x03eb (Atmel Corporation) Version: 0.00 Speed: Up to 12 Mb/sec Manufacturer: ATMEL Location ID: 0xfa144000 / 7 Current Available (mA): 500 Current Required (mA): Unknown (Device has not been configured)
The tty.usbmodem#### file definitely does not appear in the /dev folder.
I have tried a different USB cable, tried plugging it into a seperate USB hub, tried externally powering it. I even tried running a VM and connecting the arduino to it but even then the "new network interface" dialog was nowhere to be seen.
Any suggestions? Do I just need a new Arduino? I won it as a prize so I'm not sure how easily I'll be able to return it...
