hathach commented 3 years ago

Set up

Describe the bug ESP32-S2 currently doesn't detect disconnection event. Instead Suspend is detected as the side effect (since bus is idel > 3 ms). Worse, it detect suspend infinitely !!

To reproduce

  1. Run example with esp32s2 saola board with CFG_TUSB_DEBUG = 2
  2. Disconnect the usb connection while keeping the cp210x connection
  3. See error

@dhalbert suspended and disconnected are not fully supported on all ports, may need a bit of time for overall testing later on :)

Hi @hathach we updated our documentation about disconnection events, PTAL: https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-reference/peripherals/usb_device.html#self-powered-device
