I’ve plugged in my Ploopy device, but nothing is working. However, the computer recognizes that a device was plugged in.

You’re probably using the wrong cable.

Many USB-C cables only provide power, and their data wires aren’t actually connected. If your computer seems to recognize that a device has been plugged in, but none of the buttons are working and the cursor isn’t moving, the problem is almost certainly the cable.

Try using your device with a cable that you’ve verified to work with another device.
