Purpose of this article is to guide you on how to FIX the 'Prolific USB-to-Serial' driver issue with common cheap units.

In summary, this article is for: Windows XP, Windows 7, Windows 8, Windows 8.1 and Windows 10. Works on 32/64-bit.

Get the latest official Prolific USB-to-Serial Comm port (com/lpt/serial) drivers for Windows 10, 8.1, 8, 7, Vista and XP PCs. Update drivers with the largest database available. Scroll to the LPT/COM port and double click Prolific USB to Serial Comm Port; Click Drivers in the Properties section; The Driver you choose should read '3.3.2.102 with an appropriate date attached; If the date is wrong then it means the wrong driver was installed; Unplug the Serial adapter and run the steps again to install the correct driver.

And it addresses issue of: Prolific PL-2303 Driver Fix (VID_067B&PID_2303)

Driver issue will show inside your Device Manager like this:

(Notice in above picture, yellow triangle next to 'Prolific USB-to-Serial Comm Port (COM X)'. That means correct driver version is not installed.)

And if you double-click on it, you will see:

(Notice in above picture, Code 10 error. This confirms you need to install correct driver file.)

Issue will also may show messages like this:

• 'This Device cannot start (Code 10)'
• 'No driver installed for this device'
• 'Device driver was not successfully installed'

Available forum solutions to this problem are half-baked. Even vendors selling their 'USB to Serial' adapters are baffled.

Main cause of this issue is because the device you own contains a counterfeit 'Prolific' chip (China clone).

The counterfeit chip use the same Vendor ID (VID_067B) and Product ID (PID_2303) - as the authentic Prolific chips.

To solve this intellectual infringement - original Prolific company modified their newest drivers to render the counterfeit adapters unusable. Unfortunately this decision also renders all earlier adapters inoperative.

The Prolific 64-bit drivers that Microsoft supplies via Windows Update, Versions 3.4.67.325, 3.4.25.218, 2.1.51.238 and 3.4.62.293 - will not work with most adapters and therefore shows the generic 'Code 10' error.

Or you may get no error at all, but your device will still not work.

If your adapter was working prior to going to Windows Update, you can 'roll back' to the previous installed driver and all will be well once again.

However if you didn't have a previous driver installed that worked - you'll have to go through the process of removing any PL-2303 driver installation programs, the actual driver files, and the information (.INF) file, BEFORE you are able to successfully install the correct driver.

(What worsens this issue is that there are many 'Prolific Driver Removal Tools' that do not work properly.)

And Windows 8, 8.1 and Window 10 are set by default to automatically update your drivers without your permission or even notifying you of the update.

So no matter how many times you remove the driver files and reboot - the next time you insert the USB-To-Serial adapter, Windows installs the newest non-working version again.

Only 64-bit driver I have ever found that works with all the 'Prolific' adapters is Version 3.3.2.102.

Below installer program will remove all of the incompatible drivers — make a change so that Windows can never update the driver without your approval — and install the Version 3.3.2.102 compatible drivers.

The Prolific 32-bit PL-2303_Driver_Installer is a 'Program' file and therefore installed to your computer and must stay. If you want to delete it - use the Windows 'Uninstall a Program' or 'Add or Remove Program' feature - however this will also uninstall the driver itself.
