RCM Loader Not Connecting to PC: Troubleshooting Tips

RCM Loader is a popular tool for loading custom firmware or payloads onto a Nintendo Switch console. It is a small device that connects to the Switch’s USB Type-C port, enabling users to bypass the console’s security measures and run homebrew applications or other modifications. However, sometimes users may encounter issues where the RCM Loader fails to connect to their PC. In this article, we will explore some of the common causes of this problem and provide troubleshooting tips to help resolve it.

Check the USB Cable and Port

The first step in troubleshooting the RCM Loader connectivity issue is to check the USB cable and port. Ensure that you are using a USB cable that is compatible with the RCM Loader and the PC. Also, make sure that the cable is not damaged or frayed. If possible, try a different USB cable to see if that resolves the problem.

Additionally, ensure that you are connecting the RCM Loader to a functional USB port on your PC. Sometimes, certain USB ports may not be working correctly, so try connecting the RCM Loader to a different USB port to see if that helps.

Verify the RCM Loader Driver

Another reason why the RCM Loader may not be connecting to your PC is a missing or outdated driver. The RCM Loader requires a driver to be installed on your PC for it to communicate properly. You can verify if the driver is installed correctly by checking the Device Manager on your PC.

To access the Device Manager, press the Windows key + X on your keyboard and select “Device Manager” from the menu. Look for the RCM Loader under the “Ports (COM & LPT)” category. If you see a yellow exclamation mark next to the RCM Loader, it means that the driver is not installed correctly or is outdated.

To update the driver, right-click on the RCM Loader and select “Update Driver.” Follow the on-screen instructions to download and install the latest driver from the RCM Loader manufacturer’s website.

Disable Anti-Virus or Firewall

In some cases, your anti-virus or firewall software may be blocking the RCM Loader from connecting to your PC. Anti-virus or firewall software can sometimes mistakenly flag the RCM Loader as a potential threat and block its connection. To rule out this possibility, try disabling your anti-virus or firewall temporarily and see if the RCM Loader connects.

If the RCM Loader connects successfully after disabling the anti-virus or firewall, you may need to add an exception to the software to allow the RCM Loader to connect. Consult the software documentation or contact the software vendor for instructions on how to add an exception.

Try a Different PC or Operating System

If none of the above troubleshooting steps work, try connecting the RCM Loader to a different PC or operating system. Sometimes, certain PCs or operating systems may have compatibility issues with the RCM Loader.

For example, if you are using Windows 10, try connecting the RCM Loader to a PC running Windows 7 or 8. Alternatively, you could try connecting the RCM Loader to a Mac or Linux PC. If the RCM Loader connects successfully to a different PC or operating system, it may be an issue with your original PC’s configuration or settings.


In conclusion, if your RCM Loader is not connecting to your PC, there are several troubleshooting steps you can take to resolve the issue. First, check the USB cable and port to ensure that they are functional. Then, verify that the RCM Loader driver is installed correctly and update it if necessary. If you are using anti-virus or firewall software, try disabling them temporarily to see if they are blocking the connection.
