AI Overview
To install a USB-1 PL2303 driver on Windows 11, you may need to use a specific driver version, as Windows 11 doesn't always support older chipsets. Begin by identifying your chipset (e.g., PL2303TA) and downloading a compatible driver, such as version 3.8.38.2 or a Legacy driver, from a reputable source like Prolific's official site or the
GitHub repository. You can manually install the driver via Device Manager by browsing for the downloaded driver files and selecting the INF file, or by installing an executable file and then updating the driver in Device Manager.
1. Identify Your PL2303 Chipset
- Older PL2303 chipsets, such as the PL2303TA/TB/HXD, may require specific legacy drivers because they were not designed for Windows 11.
-
- You may need to download and run the PL2303 CheckChipVersion tool (from sources like Adafruit or the GitHub repository) to determine which version your device uses.
2. Download a Compatible Driver
Download the driver directly from Prolific's official website or from a trusted manufacturer's site like
Plugable Technologies.
You may need an older, legacy driver. Look for drivers on sites like GitHub which provide versions compatible with Windows 11.
