Check all your cables because it should, at least, be recognised in the Control Panel / Game Controller window.

i see it in control panel->game controls( or whateever it is) i see it there. its working on lfs but only 270°. i wanna 900. is there any other programs then logitech or wingman?

Uninstall the profiler, reboot your computer and install it again. You must have it installed properly to change the degrees.

Yup, do as Whiskey advised. Here a link for the drivers:
http://www.logitech.com/en-us/441/131 > downloads > [select] OS

So, in the Game Controller window, select the G25 and click Properties, then, click Settings(bottom right) and there you can change the rotation.

Well, this would be the first thing to do if nothing is working...
