I have the 2017 macbook pro with latest OSX as well as a windows 10 VM to test this. Sometimes loading hello world will work, but most of the time it doesnt and this is super annoying at this point. I reinstalled drivers, SimpleIDE, and rebooted multiple times. I bought a single usbc to usb adapter and didnt work. I bought a new hub thinking that was the issue too. Didnt work. Windows causes the same issue. Works sometimes and doesnt for the most part. I tried multiple USBs and even ones i know for sure work and use most of the time.
Any guidance would be greatly appreciated
