Many RC transmitters do not have built-in USB functionality, however those that do can be connected with the corresponding cable needed for that controller. IE: USB Mini/Micro etc. For those without USB connection, an external USB dongle is required. DRL has tested a few with varying results.
Below are some examples that have worked for us. Feel free to shop around to find the one that is compatible with your specific controller and operating system.
