Install the programming software (e.g., Wise Tiger CPS) if you haven’t already – it often includes the necessary USB drivers.
Alternatively, download the Prolific or CH340 driver (depending on your cable’s chipset) from the Wise Tiger support page.
Connect the USB cable to your PC, then to the radio (with the radio powered off). Windows should install the driver automatically. If not, run the downloaded driver installer.
