Seeduino XIAO failures

I’ve had two Seeduino XIAO modules (bought with connectors fitted) fail on me! They were plugged into the expansion board.
The USB connection stopped workig, but the processor was still flashing the LED on the module.

Hi leon_heller
the processor was still flashing the LED that does mean the board still working, did you select the current board on the Arduino IDE, and you mean USB connection stopped working is that mean you cannot upload the program?
please provide more detail, I can help.

USB not working so cannot select modules in Afrduino IDE. Another module works OK.

hi @leon_heller,

Can you first try to reset the XIAO and then check whether it shows up on Arduino IDE?

If that doesn’t work, try to enter bootloader mode and check whether it shows up on Arduino IDE

If that also fails, go into device manager, click on ports, and share a screenshot here.
