Hi! I'm not sure how to solve your code-on-computer-file-on-USB problem, but I have a solution! Have you heard of GitHub? It's free version web-based control, which pretty much means that you can upload your code and download it onto a different computer via the wonderful thing that is the internet! The link to Git is here:
https://github.com/. It's a slightly confusing when you first start to use it, but there are a lot of good tutorials (
https://try.github.io/levels/1/challenges/1 is my favorite) on the internet. Good luck from team 2399!
