Read steering wheel axis input?

Hi! I need to implement such scenario:

User is asked: “Please, turn your wheel left”;

Now, I need to read connected steering wheel unput, and set it to virtual horizontal axis.
Is it possible? Like, with keyboard, we do have function to read pressed keys. What about joysticks? Can I read currently active axis and e.t.c, in order to map it manually?

pleas help me i have this problem

steeringwheel input axis is not set to unity3d

for example
when i rotate to right ( +0° to +180° ) unity get me -1 to +1 float
when i rotate to left ( -0° to -180° ) unity get me on value -1 :frowning:

this steering wheel testet on many game and joystic tester and working
sorry for my bad english
