@Phaedrux
Thank you for chiming in! The board was bought from your reseller Reprapworld in mid september

Here we go

Yes, just the USB-cable (same way that we've done with 20 or so other boards with no issues), and the board was straight out of the box. It had been sitting on our shelf for a few months before we commissioned it, but it has been sitting in its original packaging in an untouched box for that time

Hi!
We were setting up a Duet2 Ethernet the other day which a few seconds after plugging it with a USB cable (nothing else attached) started to crackle and let out a fair amount of magic smoke from the U3 chip...
@dc42 Could this perhaps be a faulty chip? I read that there has been some faulty U3 chips in the past, but those threads were from quite a while ago.
