Ahh gotcha. Didn't know there were charge-only cables. Maybe my hub is having power issues - I noticed the indicator light for the port seems to flicker when the Teensy is connected...
Hi,
I'm running into some wackiness with USB hubs and cables while trying to connect a Teensy 3.5 to my Mac. Initially, the Teensy wasn't even connecting, and I eventually realized specific cables seemed to not work...
