usb_modeswitch is working when I am running the command twice.

       I am using libusb-1.0.21 version , usb_modeswitch-2.4.0 and kernel-3.10.14 ,when the first time I am running usb_modeswitch command its is not switching and when I run the command for second time it is switching.I don't know why I have to run it twice to make it working,I want to do this only once.Below is the complete log ,Please help me to resolve this issue.
