Warning Notice:
It is recently confirmed that counterfeit (fake) PL-2303HX 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 (Error Code 10).
