Code 10 prolific usb serial windows 10 install#
Only 64-bit driver I have ever found that works with all the "Prolific" adapters is Version 3.3.2.102.īelow 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. 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. What aggravates this issue is that there are many "Prolific Driver Removal Tools" that do not work properly!Īnd 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. 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. 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. Or you may get no error at all, but your device will still 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 therefore issues the generic "Code 10" error.
Unfortunately this decision also renders all earlier adapters inoperative. To combat this, original Prolific company made changes to their newest drivers to render the counterfeit adapters unusable. The counterfeit chip use the same Vendor ID (VID_067B) and Product ID (PID_2303) as the authentic Prolific chips. Main cause of this issue is because the device contains a counterfeit "Prolific" chip (made in China). Even companies selling these USB to Serial adapters are confused. Internet is filled with pages discussing this problem - but no one seems to know what causes it.
