Cannot recognize device

Post by jentheteacher »

One of my brand new circuit playgrounds cannot be recognized when plugged in. I have tried it on different devices and with new cables. All the other devices in my kit work with no issues on the same device. Any suggestions on how to get a replacement?

I have an older models of the circuit boards. When using code.org, the lesson does not recognize the circuit board when it is plugged. I tried different usb ports....nothing works....help.

But which one? Classic? Express? See https://learn.adafruit.com/adafruit-cir ... vs-express.

They are Express ATSAMd21 @ 48MHz.
Does the battery need to be connected? I just plugged one in of the cord to the circuit board then plugged in the usb drive. The message on the screen say that it does not recognize a serial port.

DOMException {stack: "Error: Failed to execute 'requestPort' on 'Serial': No port selected by the user."}

This is the message shown in my Debug category in code.org......

Have you confirmed that you have a data USB cable and not a charge/power only one?

When we purchased the kit, it came with a usb cord so I'm using what your company supplied.

OK, then that's not the problem.

What happens if you double-press the reset button on the board?

Can you try uploading a simple sketch using Arduino? The blink test sketch will suffice to test whether the board is working.
