Unable Yo Install Qmobile A900i Drivers - android_winusb.inf-file driver

Hi everyone!

I am trying to connect my Qmobile A900i with Qmobile PC suite but failed. When I turn on the debuggin mode of my phone, in device manager I get my device name in other devices,

I think i need to make some modification to android_winusb.inf-file driver but i do not know how to do it.
Best Regards.
