STM32 VSP - only works when USB freshly connected, not on reset.

Here is the firmware, it's very close to something generated from cube.

  • ST link V3
  • Arch Linux

When the device is initially plugged in, I can...

screen /dev/ttyACM1 115200

I then see my hello world printing in a loop. If I hit the reset button on the MCU hello world will stop printing. This is very problematic for debugging.

Has anyone seen anything like this before?
