	I have an ESP32C3, and all the serial ports on it have been used. I cannot use the serial port to upload. The ESP32C3 data sheet says that it can be uploaded directly through USB, but I don’t know how to implement it in visual micro.

	There is a USB-JTAG interface on the board, which depending on the specific board you have may require additional external wiring. This can also be used for Hardware Debugging, which can be seen on the below page: https://www.visualmicro.com/page/ESP32C3-USB-Debugging.aspx We have not implemented the USB-JTAG upload currently in the drop down lists, however we can provide overrides to try and get this working for you. Alternatively if you have an ESP-PROG (or other debug probe) this can also be used for upload and debugging. If you can confirm which specific board you have we can advise if any external wiring is needed to use the USB-JTAG approach.
