Removing a Prolific Serial to USB Driver from Windows
At defiant duck, I had one POS terminal that would not remove a prolific USB to Serial driver through control.
Give the steps below a try. http://usglobalsat.com/forum/index.php?topic=3554.0
If you're unable to install or remove the driver from the list of programs, you can utilize a program called CCleaner. For download, please click here: (http://www.filehippo.com/download_ccleaner/download/3a3e44d3c4dbe3b50634a122bf7000d6/). When it's done, install the application and please follow the instructions below:
1.) Open up the CCleaner.
2.) Go To Tools.
3.) Select the PL-2303 USB-to-Serial from list of the Programs to Remove. Click Delete Entry.
4.) It will ask you to proceed with the Uninstall process. Press OK.
5.) The driver is completely removed.
This worked for me, from there I used a PL-2303 USB to Serial Driver to reinstall.
It took a few attempts of uninstalling and reinstalling, eventually, when i plugged the RFID scanner in, it was assigned a com port by windows.
The peripheral worked successfully.
I have attached the driver that I used.
