The Kinamax TS-9900 is a legacy device supported by the Prolific PL-2303 driver architecture. Drivers are free and widely available. However, users should be prepared to troubleshoot potential driver version conflicts (Code 10 errors) by rolling back to older driver versions if the newest official driver does not recognize the hardware.
To get your up and running, you'll need the specific drivers for its internal chipset. Since Kinamax does not have a dedicated official support site, you should use the drivers for the Ralink 3070 chip , which powers this device. Download and Driver Details kinamax ts9900 driver download free
