If you have previously used the PL-2303 (with W7) and upgrade to W10, it's simple because the previous versions of the drivers are still on your computer.

The version driver (ser2pl.sys or ser2pl64.sys) should be something like 3.6.78.350īut this one doesn't work anymore with old PL-2303 hardware. You can check it, using the configuration panel: watch the COM and LPT section, you should have the "Prolific USB-to-Serial Comm (COM X)". Indeed, when installing W10, the device driver for PL-2303 is the latest version. May be, a solution will be to use the old W7 drivers version into W10.

Prolific's guys are fun when they said : " Prolific recommends to use It's a shame from Prolific to not support this devices, because they are still used (my LED badges are less than a year old,Īnd use EOL PL-2303 HX).
