teensy stops working sometimes

Recommended Posts

I've got a teensy for addressable LED's and on occasion I'll boot up the virtual pinball machine to find that the addressable LED's are not working. 

I can usually get it working with some combination of:

1) pressing the reset button the teensy

2) Unplugging the RJ45 cables from the OctoWS2811 

3) unplugging and plugging the USB cable from the teensy

4) powering down the PC

5) unplugging the PC and waiting for 10 or 20 seconds for my power supplies to discharge


Those 5 steps are involved in getting it working, but I don't which one or the magic that's making it work.  I don't think any one step by itself was helping.  I do always get it to come back up and work but I'm at a loss as to why it would do this. 


What trouble shooting steps should I take next time this happens?

Try a different USB cable
Try all the other USB ports on the computer
It's possible it could be the teensy
I wish I had more ideas, I've never experienced this situation
