OK ,
I bought a logitech G25 stearing wheel. It installed fine. but inthe calibration part it all buttons and pedal work except the wheel it self.
i am running winxp
can any one help?

I go for a reinstsall... Just a word of caution regarding USB...be sure to check the documentation for the installation. Most USB require the software to be preinstalled and then the device...

Something might have become corrupted during the install... Or, the wheel might be defective.

You might want to contact Logitech tech-support if this is under warranty and see if they have any troubleshooting advice.
