[Mac + Analog Discovery 2 + Waveforms 2015: No device detected]

Well if we are having an "my FTDI is bigger than yours" contest,  I once had over 50 FTDI cables hooked to my laptop at the same time ;-).

I was worried that there might be an FTDI conflict but I can still terminal into my linux devices and log debug data with cool term so not seeing any issues.  I did check on initial connection and I did see the the AD2 device in /dev even before is started functioning.

I did say that they should hook up several dozen of these to macs to see what the problem might be.  Maybe they should just hire you and I and we can fix it for them :-).

Just wanted to add that I just purchased one of these and hooked it to my Mac, after installing the software, and it did not work.  Did a power cycle and tried plugging in to different USB ports and still no go.  Left it connected for a while to my powered USB hub (which I had initially tried and it did not work) while I read this forum and then started up and everything worked fine.  Might want to try hooking a couple dozen to a Mac laptop and seeing if any have a hard time coming up.  Mac laptops are notorious for not being able to drive instruments via USB.
