Solution for Prolific PL-2303 USB to serial driver problems in Windows VISTA and Windows 7

Today I faced one irritating issue. And i realised that many among us are facing the same issue. So i decided to help them through my blog. Many of the USB to serial converters available in the market are using Prolific chips and the drivers shipped with the product come from prolific. These wont get properly installed in the OS versions mentioned in the heading and a yellow mark appears near the device seen in Device Manager showing that the driver is not properly installed. The device manager will show the error as "The device cannot start (Code 10).

I had tried restarting the system, updating the driver after downloading the latest version, using windows update to find the correct driver etc. Also checked the internet and tried around 10 drivers from forums. And finally after three hours of hard work, a driver actually did the job.

Please use the below driver for proper working of your USB to serial converter. Hope I helped you in your problem
