Are you having trouble connecting your radio to FPV simulators, where it’s not recognized as joystick on your computer? Here is the quick fix.
Check USB Option
Go to “Model Setup“, scroll down to the option “USB Mode“, and select “Ask“.
It was probably on the wrong option (USB Storage), that’s why every time you plug in the USB, it’s showing a drive instead of joystick on your computer.
When it’s set to “Ask“, you will get a prompt like this:
What I normally do is, create a model profile just for simulators, set the USB option to USB Joystick (HID) and turn off RF Internal and External to save power.
Why Is This Suddenly a Problem?
If you used to have a really old OpenTX running on your radio, and only recently you updated the OpenTX firmware, you could have this issue. This is because the new “USB Mode” option was only introduced in OpenTX 2.2.
Before OpenTX 2.2, there wasn’t an option in the menu to choose between “mass storage” or “joystick”, you had to make the decision when flashing OpenTX firmware, “massstorage” was a build option.
It’s great to finally have this option in the menu, but that also confuses many people due to the large amount of outdated info out there. I hope this clears things up!
