The final definitive guide for fixing the failure of the (PL2303) Prolific USB-to-Serial Comm Port driver in Windows 10, step by step:įirst, install the latest driver for the PL2303 USB-to-Serial adapter from Prolific's website thenĭownload older driver that is compatible with Windows 10:ġ. PROLIFIC USB-TO-SERIAL COMM PORT WINDOWS 10 I've tried changes the System settings for updates but without success. Is there a way to stop Windows 10 from updating these drivers every time the cable is inserted? However, when I unplug the cable & re-insert, Windows 10 will automatically update the drivers to the NON-Working ones & I have to then re-select the v3.2.0.0 ones every time. If I now update drivers back to v3.2.0.0 it works & I have a singe interface cable that works on both Windows 10 & Windows XP & plug in the interface cable, Windows 10 will then update drivers BUT with Code 10 error.

If I uninstall all relevant drivers, then install my original Vista Driver v3.2.0.

The newer interface cables when connected to Windows 10 automatically installs the drivers & works on Windows 10, but will not work on Windows XP (I don't have a driver disk for this cable but it is CH340 v.8).

The older which used to previously work on Windows 10 still works OK on a Windows XP Laptop proving that the interface is still functional.

Have now got things working in a rather 'round-about' way.
