prolific usb to serial comm port 3.4.25.218

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.

In Windows 8, 8.1, and Window 10 are by default set to automatically update your drivers without your permission.

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.

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.

The below installer program will remove all of the incompatible drivers, make a change so that Windows can never update the driver without your okay, and install the Version 3.3.2.102 compatible drivers. The only 64-bit driver I have ever found that works with all the “Prolific” adapters is Version 3.3.2.102. Or, you may get no error at all, but your device will not work.

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 issues the generic “Code 10” error. Immediately I checked the Device manager and found the error code 10 with the following message: “Device driver was not successfully installed” I ended up writing this post when I connected the Prolific USB to serial device to my Windows 7 64-bit OS and installed the officially downloaded driver and found that it is not working and Windows has thrown the following error messages: This is a FIX for Prolific USB to serial on Windows 32 and 64-bit Operating Systems – Prolific PL-2303 Driver Fix (VID_067B & PID_2303).
