What is considered a gamepad to Steam? SOLVED

I imagine taking the time to find out if it works with just your logitech controller wouldn't be long, though I don't see why it won't work.
If it doesn't work, you can always download some sort of emulator that makes it look like your logitech is a 360 controller

Well, the gamepad inputs are standardized, every controller working on computer will work with Steam.

I have a Logitech Dual Action gamepad too, and it's been compatible with it since forever.

I wonder if a wheel would work... LOL controller, nope, I'll never buy one of those.

Most games only works with 360 controller and logitec 710. Some may work with others but not many.
Try your logitec fşrst. If it doesn't do the job, try this:
