Genuine

We use only genuine Prolific serial chipsets in our adapter. Some inexpensive serial adapters use cloned Prolific serial chipsets that will not work with the latest Prolific drivers, both those available for download and the drivers embedded in Windows. Because we only use genuine Prolific chips, our adapter is always compatible with the latest drivers from Prolific.
