1 year ago This is expected behavior: Mu detects the board by looking at the CDC interface name, using https://github.com/adafruit/Adafruit_Board_Toolkit. See compatible_board() in https://github.com/mu-editor/mu/blob/master/mu/modes/circuitpython.py. You could change the code there or in the toolkit to detect your board. But the current choice is for vanilla boards.
Because CircuitPython can present two serial channels, the interface name is used to detect the correct one (the REPL one, not the data one).
Mu used to use a list of USB VID/PID's, but that required constant maintenance.
You don't have to use Mu: you could use PyCharm or VSCode, or use Mu in a "manual" mode and upload code to CIRCUITPY yourself. You can use any terminal program (tio is good) to connect to the right port.
What were you trying to do?
Edit code for Raspberry Pi Pico W
What steps did you take to trigger the issue?
I built circuitpython but changed the code to update the USB_INTERFACE_NAME, afdter doing this and flashing the new firmware
What did you expect to happen?
Mu to continue detecting circuitpython
What actually happened?
Mu was not able to detect the pico W board. The board was working fine and doing what it was programmed to do.
Operating System Version
Window 11
Mu Version
1.2.0
Other Info
When I rebuilt circuitpython with the original USB_INTERFACE_NAME it was again able to detect the pico W board

It must have a version of MicroPython (or CircuitPython) flashed onto it before the REPL will work.
Finally, press the device's reset button and wait a few seconds before trying again.
