Issue with Teensy 4.1

I can't get my teensy 4.1 to work with any lighthack codes. I've tried the original and all of Druuka's and sstaub's codes. Below are the messages I get when I plug the teensy in. Any idea what the problem is?

  • If you are using the same computer for both programming the teensy and also running nomad you have to turn off one of the programs for the other one to work.  If both are on you will have problems programming the teensy and or connecting to the console as both programs are trying to use the usb interface at the same time.
