Xbox cloud pc gaming bug whilst Hotas warthog joystick is connected

Only the standard Xbox controller works at this time via the cloud. There is no word on when that may change. You will have to purchase a Series console or play on PC to use your HOTAS

When I bought this HOTAS in the details it said compatible with Xbox one. So are you saying I need to buy another joystick or an Xbox series X or S?

this is from the
Thrustmaster page for those pedals

"THE TFRP RUDDER–Thrustmaster Flight Rudder Pedals: DESIGNED FOR ALL USERS Compatible on PC with all joysticks on the market Also compatible on PS4™ with the T.Flight Hotas 4 joystick*/** and on XBox One™ with the T.Flight Hotas One joystick "

it looks like the pedals are compatible but you might need to get the T.Flight Hotas One joystick.

According to the instructions:

1. Set the selector switch on the joystick from PC to Xbox.

2. Connect the USB cable to your console.

3. Turn on your console.

4. Launch a game that supports the joystick/Flight Stick mode.

You may also need to update its firmware on this page:

Thats because the Thrustmaster Warthog HOTAS is not compatible with xbox.

Windows only.

If you only want to use the joystick, then no.

Only officially licensed Xbox controllers will work on the console (with the exception of standard HID USB keyboards for text entry).

However, the official Xbox Adaptive controller that is aimed at gamers with disabilities also has two USB ports, and supposedly some PC joysticks work on that.

This is however a "your mileage may vary" thing, as the Joystick probably will only be able to use it's X and Y axis, and not much else.

If you want a fully fledged Joystick that you can also use on the PC, you might want to look at the Thrustmaster T.Flight HOTAS One: http://www.thrustmaster.com/en_US/products/tflight-hotas-one
