USB Drivers not working for HL6528RD

I am using USB port of HL6528RD and connecting it to my PC(windows xp sp3)whenever i connect USB to pc a pop up indicating “USB Device not recognized” appears.After installing the driver provided on website(MS_USB_ComPort_Driver_exe_v1.1032.1),it still remains the same. The ports are not shown in Device Manager and status still remains as"UNKNOWN DEVICE".
Kindly suggest how this can be resolved.
