To fix this issue, there are several ways to resolve it. Three efficient methods are mentioned below: 1. Update the driver.

How to Fix Prolific USB to Serial Driver Not Working on Windows 11/10?

If you’re using a USB to serial port adapter on your computer, you may experience issues when trying to connect devices. This problem can occur if the USB to the serial driver isn’t installed or is outdated. This can lead to various errors, including “This device cannot start” or “Code 10”.

The most common issue is when the Prolific PL2303 USB-to-Serial driver fails to install properly on Windows 11. You can check the driver’s status by opening the Device Manager and scrolling down to the Ports (COM & LPT) category. You can also find the driver by searching for it in the search box.

Once you’ve located the driver, double-click it to open and extract the files. Then, click the “Update Driver” button to install the latest version of the software. After the update, you should be able to connect your serial devices without any issues. If you still have trouble, try the following solutions: 1.

1. Update the Driver:

Many people use legacy equipment that requires a serial port. To make it work with modern computers, they often install a USB-to-serial converter using chipsets from Prolific. While this is a simple solution, it can be complicated to get the drivers working properly. This is because Windows updates can impact virtual serial port drivers, causing them to stop working.

To fix this problem, you need to update the driver for the USB-to-serial converter. You can do this manually or automatically. The automatic way is recommended, as it will save you time and effort.

First, download the latest driver from the manufacturer’s website. Then, follow the instructions to install it on your computer. It should only take a few minutes. After the driver is installed, reboot your computer. Then, check the status of the device in the Device Manager. The device should now appear in the list of COM ports. If it doesn’t, then you should try to download and install a different version of the driver.

2. Uninstall the Driver:

Many devices require device-specific software and drivers to be installed before they can be used. Make sure to follow the installation instructions from the manufacturer.

Some USB devices will not appear in the list of available ports (COM and LPT) in Windows 10. This can be a real headache if you need to use those devices for work or play.

Open the Device Manager and select View then choose Show hidden devices. Expand Other devices, right-click on each USB driver, and select Uninstall. If you are asked to confirm, click Yes.

Alternatively, you can try downloading the latest driver from your motherboard’s website and installing them manually. But if you’re not comfortable with manual installations, or you don’t have the time or patience, we recommend using a third-party tool like Driver Easy. This tool can automatically detect your system configuration and find the best-matching driver for your computer. It can also download and install the driver in just a few minutes.

3. Reinstall the USB Serial Port Driver Windows 11:

If you still see a “Code 10” error when connecting your USB to the serial adapter, reinstalling the driver may resolve the issue. To do so, follow these steps:

First, make sure that your adapter is powered on and connected to a working computer. Then, open the Device Manager and expand the Ports (COM & LPT) option. You should see your USB to serial adapter listed under “Universal Serial Bus controllers”, as shown below.

Once you see the device in Windows Device Manager, launch EaseUS DriverHandy. The software will automatically find and update the faulty USB to the serial converter driver for Windows. Moreover, it will back up the old drivers and keep them updated as new updates are released. This will save you time and avoid errors caused by manually downloading and installing the drivers from the Internet. Additionally, the software also comes with features to optimize your PC’s performance. Try it now!
