USB port disappears when powered down #99

Closed elin05 closed 4 years ago

elin05 commented 4 years ago

I have the line LowPower.powerDown(SLEEP_8S, ADC_OFF, BOD_OFF); in my loop()

But now my Leonardo's USB port disconnects after a few seconds after reset. The port won't remain active long enough for me to upload a new sketch to overwrite the one with LowPower.powerDown(SLEEP_8S,...).

  1. Does powerDown() effectively disable the USB port?
  2. How can I now upload a new sketch to my Leonardo?

I resolved the issue by using an AVR programmer to reprogram my Leonardo.
