Hello, I'm unable to program any sketches onto Teensy 4.0, failing with the error of "No Teensy boards were found on any USB ports of your computer."
1. I tried two different USB cables to the same effect that are known good for programming other devices
2. I tried two different computers that have been able to program other microcontrollers
3. I tried using PlatformIO (latest) and Teensyduino (Arduino 1.8.12).
The orange LED blinks the standard blinking program that comes with Teensy 4.0. The only thing that I've tried to do so far is to solder on headers and program it. It shows up as a HID device when I plug it into the computer. When I press the pushbutton on the Teensy 4.0 nothing happens: the Teensyduino loader doesn't change or say that the program is uploaded. I have also tried holding it down but the program continues to run the blink program (LED blinks at 1Hz).
