My first post, thanks in advance for forgiving/correcting any posting violations I may make.
I'll gladly post code if asked but i don't see how that would be of use in this case.
I've been working with Teensy 3.5 & Audio Board the past few days that I had powered/connected by USB to macbook. In addition I have a small strip of 24 WS2812b connected to pin 24 (data) powered by separate regulated 5v supply. This has all worked perfectly well until an hour ago when I needed the USB port for something else. When I replugged the Teensy back into the USB port - nothing. No smoke, no sound, but no life from the Teensy either. I tried plugging it in to another previously know working laptop's USB but still nothing. Checked LEDs, they are fine.
I assume I blew the Teensy but I'm not sure what I did wrong, it had been working fine for several days. Any ideas what I broke & how to prevent it in the future?
Originally I had the LEDs GND connected to the Teensy GND pin located across from pin 24, but the LEDs worked fine without so I disconnected it two days ago. Could that have led to blowing the Teensy?
A sincere thanks for any advice.
