To check if you have a data cable that will work, plug in your device and navigate to `Device Manager > Ports` and ensure the device is shown. You should see something like `CP210X USB to UART Bridge Controller`.
If your device is showing up under `Device Manager > Ports > Other Devices` you need to install the driver from Silicon Labs for the [CP210X USB to UART bridge](https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers)
