Prolific Leo''s Notes

Prolific. The Prolific 2303 is a USB to serial controller. Cloned versions of the controller was commonly found in serial adapters from Ebay/China until around 2014 when Prolific began bricking cloned devices by overwriting the firmware via the drivers. Since then, most cheap serial adapters on Ebay use the CH340 or CP2102 controllers instead.
