Why Your CH340E Is Giving Error Code 10 and How to Fix It
If you're seeing Error Code 10 while trying to use a CH340E USB-to-serial adapter, it can be frustrating. But don't worry! This error typically indicates a driver issue, hardware problem, or a conflict with other devices on your computer. Here’s a detailed step-by-step guide to help you diagnose and resolve the issue:
Understanding Error Code 10:Error Code 10 usually appears in the Device Manager on Windows and means that the device (in this case, the CH340E) is unable to start properly. This can happen for a variety of reasons, including driver problems, conflicts with other hardware, or even faulty cables.
Step-by-Step Guide to Fix Error Code 10 for CH340E: Check Device Connections: Step 1.1: First, ensure that your CH340E adapter is properly connected to your computer. If you’re using a USB cable, try replacing it with another one to rule out any physical connection issues. Step 1.2: Try connecting the device to a different USB port. Sometimes, a specific port might have a malfunction, or there may be a conflict with another device. Update or Reinstall the CH340E Driver: Step 2.1: Open Device Manager by pressing Win + X and selecting "Device Manager." Step 2.2: Locate the CH340E device in the list. It might appear under "Ports (COM & LPT)" or "Universal Serial Bus Controllers ." If you see a yellow warning icon next to it, this indicates a problem with the device. Step 2.3: Right-click on the device and select "Update Driver". Select "Search automatically for updated driver software" to let Windows search for and install the latest driver. Step 2.4: If Windows can't find an update, go to the CH340E driver’s official website and download the latest version. After downloading, run the installer to update the driver manually. Uninstall and Reinstall the CH340E Driver: Step 3.1: In Device Manager, right-click the CH340E device and select "Uninstall device." Step 3.2: Once the driver is uninstalled, disconnect the CH340E from your computer and restart your computer. Step 3.3: After rebooting, reconnect the CH340E device. Windows should automatically attempt to reinstall the driver. Check for Conflicting Drivers or Devices: Step 4.1: Sometimes, other drivers can conflict with the CH340E, causing it to show Error Code 10. Check if there are other devices connected to the same USB controller. Step 4.2: If possible, temporarily disconnect other USB devices (like printers, external drives, or even other serial devices) and check if the CH340E works without any conflicts. Update Your Operating System: Step 5.1: Ensure your computer is up-to-date by installing the latest Windows updates. Sometimes, Windows updates include bug fixes that might resolve driver conflicts or hardware recognition issues. Step 5.2: To check for updates, go to Settings > Update & Security > Windows Update, and click Check for updates. Try on a Different Computer: Step 6.1: If the CH340E still doesn’t work after performing all the steps above, try using the adapter on a different computer to see if the issue is specific to your system. Step 6.2: If the device works on another computer, the issue is likely related to your original computer’s USB ports or software environment. Check for Hardware Issues: Step 7.1: If none of the above steps solve the problem, the CH340E itself might be faulty. Check if the adapter shows the same error on other computers. Step 7.2: If the issue persists across multiple devices, it may be time to replace the CH340E adapter. Conclusion:Error Code 10 related to your CH340E USB-to-serial adapter typically points to a driver issue, hardware conflict, or a device malfunction. By following the above steps—checking your connections, updating or reinstalling drivers, resolving conflicts, and testing on different machines—you should be able to fix the issue. If the problem persists despite all efforts, consider replacing the device.
