SparkFun Thing Plus ESP32-C6, unable to connect via Serial

Development Boards ESP32
1

I recently purchased two SparkFun Thing Plus - ESP32-C6 boards and I’m unable to connect to connect to either one using the Arduino IDE or Putty. They both power on fine when connected to USB-C and run the sketch that came flashed (RGB LED cycling through colors) but all of my attempts to flash with a different sketch or simply connect using Putty result in the following error:

'A device attached to the system is not functioning.'

I have other ESP32C6 dev boards that I can connect to without any problems, but both of my Sparkfun boards are unresponsive.

Does anyone have a suggestion on how to troubleshoot this?

You might try a different USB cable. A flakey cable can give that error message.

Yep, that was it. Thanks for the suggestion!
