Hey mate,
This is probably off topic here. Maybe you can close this issue and send me your schematics (old, new), gerbers (old, new), etc. I will see what I can do for you.
Cheers JP
Thanks so much, I'll attempt to send you an email / come other form of social
Can i start off by saying, this issue is not caused by this library (although we do use it).
But i need some experts and don't know where else to turn!
We have a custom board based off the atmega32u4, with an external 16MHz crystal oscillator. At present we use the Leonardo bootloader, but have also used the Sparkfun Pro Micro one as well. The history is that we made a batch of these boards to test them, they all worked perfectly. Connect seamlessly to Windows, ChromeOS & Mac and show up as serial ports. Then we made a larger batch, now, these new boards connect fine on Windows & ChromeOS, but they don’t connect to Mac.
Thoughts i’ve had, with their counter argument:
If anyone has any advice for things to check I'd be most grateful. Even advice on other forums / areas i could post on.
Many thanks and much love / coffee / beer / cold hard cash to anyone that can point me in the right direction.
