HL 340 USB to Serial Driver: Understanding the Authenticity and Compatibility Issues

The proliferation of counterfeit products has become a significant concern in the technology industry, including the world of USB to serial drivers. Prolific, a renowned manufacturer of USB to serial controllers, takes serious measures to prevent the distribution of unauthorized or counterfeit PL-2303 drivers. In this article, we will delve into the importance of authentic drivers and the compatibility issues associated with counterfeit products.

Prolific's stance on counterfeit products is clear: they prohibit the distribution of any PL-2303 drivers without written permission from the company. The manufacturer warns customers and consumers against buying counterfeit products, which can lead to severe consequences, including legal action. Counterfeit IC products may appear identical to authentic ones but often have poor quality and can cause compatibility issues with Windows drivers.

The warning extends to those selling counterfeit products in the China market, which has been a hotbed for fake PL-2303HX (Chip Rev A) USB to Serial Controller ICs using Prolific's trademark logo, brandname, and device drivers. It is essential for customers to verify the authenticity of products before making a purchase.

Prolific recommends using the PL-2303GC chip, which provides optimal performance and compatibility with Windows operating systems. The company has also made available the PL2303 CheckChipVersion tool program to help users identify the correct chip version on their devices.

In terms of technical support, Prolific has discontinued support for Windows Vista, XP, 2000, 98, and Windows ME drivers. However, users can run the PL2303 CheckChipVersion tool program in Windows XP/Vista/7 to check the chip version. Furthermore, Prolific does not support Windows 11 and higher for certain EOL chip versions, including the PL-2303HXA/TB/HXD/RA/SA/EA.

For users of newer operating systems like Windows 8/8.1/10, it is crucial to note that Prolific's drivers are not supported for certain EOL chip versions, such as the PL-2303HXA and PL-2303X. The company has also included certification reports, user manuals, driver release notes, and checkchipversion tool programs in the installer package.

In conclusion, it is vital for customers to be aware of the authenticity and compatibility issues associated with USB to serial drivers. Prolific's commitment to providing high-quality products and technical support ensures that users can rely on their drivers for seamless communication between devices. By understanding the importance of authentic drivers and staying informed about compatibility issues, customers can make informed purchasing decisions and ensure optimal performance from their devices.
