Warning Letter on Counterfeit Products   Hot News

 

Warning Notice:


It is confirmed that counterfeit (fake) PL-2303HX Rev A USB to Serial Controller ICs using Prolific's trademark logo and device drivers were being sold in the China market. Counterfeit IC products show exactly the same outside chip markings but generally are of poor quality and causes driver compatibility issues. We issue this warning to all our customers and consumers to avoid confusion and false purchase. Only buy from Prolific authorized distributors.

Please be warned also that selling counterfeit products are illegal and punishable by civil and criminal courts according to the trademark, copyright, and intellectual properties laws and regulations. Prolific will take proper and severe actions to cease and confiscate these counterfeit products. Prolific also prohibits the distribution of any PL-2303 drivers (including download links) without written permission from Prolific.

Prolific advices end-users to only purchase branded cable products with company name contact information for service and support in case you suspect a counterfeit chip inside. You may also contact Prolific to provide the vendor information.

PL-2303HX Rev A (or PL-2303HXA) also has been discontinued (EOL) since October 2012 and does not support Windows 8 onwards. Prolific advises users to purchase cables/adapters with PL2303HXD (HX Rev D) or PL2303TA chip.
