About self-powered device VBUS monitor question
Posted: Thu Dec 14, 2023 1:12 am
I would like to ask, what is the role of ESP32-S3 TinyuSB's VBUS monitoring, and what are the consequences of not monitoring VBUS for self powered devices? Will there be any issues with USB sending data if the USB cable is disconnected and reconnected without monitoring VBUS?
I made a self powered device using ESP32-S3 as the main chip and used it as a USB CDC device. I also set up monitoring VBUS pin during the installation of the tinyuSB driver. But there is still a situation where the data sent by USB to the PC cannot be displayed when reconnecting after USB disconnection. I am not sure what the reason is, can anyone help explain it?
