Here are some solutions if your laptop is not recognizing a new USB device after connecting it:

1. Check the Connections: Make sure that the USB device is securely plugged in to the captive port of the laptop. Check if the USB device works on another computer.
2. Update Drivers: Check the manufacturer website for updated drivers and install if necessary. You can also try searching and downloading drivers from online resources.
3. Restart Computer: Restarting the laptop with the USB device already connected may trigger the recognition process.
4. Reinstall Device: Uninstall the device and then connect it again. This will allow the laptop to detect it freshly.
