[Thirumalesha N]

Dear Sir,

               I'm testing pmc type SM502 Graphics card which as USB, Audio
and Display Interfaces. I'm unable to test usb with sm502 display.

               Logitech Optical wheel mouse connected to USB port. Is there
any configuration to do in xorg.conf file?

            OS --> Redhat 5.5 Entrp. and kernel linux-2.6.21

            Any suggestion or help greatly appreciable....

Thanks & Regards

Thiru N
