Hi there! It looks like you're experiencing an issue with your CooDisk device not being recognized. Let's work together to resolve it.

1. Remove and Reinsert: First, please carefully remove the CooDisk from your iPhone and then reinsert it, ensuring that it fits snugly into the port. If you have a case on your iPhone, it may help to take it off to ensure full connection.

2. Check for Debris: Look inside the Lightning port on your iPhone for any dust or debris that may be obstructing the connection. You can use a soft, dry toothbrush or a can of compressed air to clean it gently.

3. Restart Your iPhone: Sometimes a simple restart can help. Hold down the Power button until the "slide to power off" slider appears, and turn off your device. Once it's fully off, turn it back on.

4. Check the App: Make sure you have the CooDisk app installed and updated to the latest version. Open the app after reinserting the device to see if it's recognized.

5. Test on Another Device: If possible, try inserting the CooDisk into another compatible device (like another iPhone) to see if it gets recognized there. This can help determine if the issue is with the device or the CooDisk itself.

6. Update iOS: Ensure that your iPhone is running the latest version of iOS. You can check for updates by going to Settings > General > Software Update.

If these steps don't resolve the issue, it could be a deeper hardware problem with the CooDisk itself, and I may need to look into further options. Please let me know how it goes or if you need more help! Are you satisfied with the solution I provided?
