The adapter uses the standard USB Prolific VID and PID of 0×2303, which is recognized by all of Prolific’s standard drivers.
Please visit the Prolific PL2303 driver download page for all other operating system options. Login as guest with the password guest and choose USB Serial/Parallel under USB Smart I/O Controllers.
