Prolific USB-to-Serial Comm Port (COM1) Driver Download
The drivers provided on this page are for Prolific USB-to-Serial Comm Port (COM1), and most of them are for Windows operating system. Before downloading the driver, please confirm the version number of the operating system installed on the computer where the driver will be installed. If the system version number does not meet the driver requirements, it may cause some unexpected problems. In the case of determining the operating system version number, it is recommended to download the 5-star driver first.
In addition, as long as your downloaded driver version can make the system work normally and stably, you don't have to excessively pursue the latest version of the driver. This is because the new version of the driver is to solve some BUGs in extreme cases, or to improve a little bit of hardware performance, but it may also bring some new unpredictable problems.

Haven't found the right driver yet? Are you facing difficulties in the driver search process?
1. The drivers you found aren't compatible.
2. You don't know how to search for drivers.
3. Your device isn't installed with drivers and appears as an "unknown device" in the system. You don't know how to find drivers for it.
This website offers a new method for finding drivers, a precise and fast way. Click here to use the new feature.
Use the search function to find the driver you need
Many hardware names are usually named after the chip model, and each chip model has its own dedicated driver, so as long as you know the chip model used by the hardware, you can find the right driver. For example, if your graphics card is named: "AMD Radeon RX 580", while actually the core chip model used is: "Radeon RX 580", then enter "Radeon RX 580" or "RX 580" to find the driver.
If you have a laptop or an all-in-one PC, you can also use the product name to search, and then go to the download page which has all the drivers for this machine (including: graphics card, network card, sound card, etc.). For example, if your laptop product name is: "Dell A6-9220e Inspiron Flagship", then type "Dell A6-9220e" to find all the drivers for this laptop.
Search steps:
1. Enter a keyword in the input box and click the "Search" button
2. In the query results, find the driver file you need, and click the download button
Driver Finder:
• Can't find the required driver files?
• Don't know how to find driver files?
• Unable to download driver files due to unstable network?
You can try using this driver file finder. The method of use is very simple. The program will automatically list all the driver files available for your current system. You can install drivers for devices that do not have drivers installed, and you can also upgrade drivers to the latest driver version for devices that have already installed drivers. Click here to download the driver finder.
