Thanks for the reply,

I wrote the code using libusb library. After opening the device successfully I tried to claim the interface. But its giving error while claiming that device. When I write the detach kernel function only it can able to claim the interface.

#ifdef LINUX
        libusb_detach_kernel_driver(devh, 0);
#endif

        r = libusb_set_configuration(devh, 1);
        if (r < 0) {
                fprintf(stderr, "libusb_set_configuration error %d\n", r);
                goto out;
        }
        printf("Successfully set usb configuration 1\n");
        r = libusb_claim_interface(devh, 0);
        if (r < 0) {
                fprintf(stderr, "libusb_claim_interface error %d\n", r);
                goto out;
        }
        printf("Successfully claimed interface\n");

        r = libusb_bulk_transfer(devh, ENDPOINT_INT_IN, buf,sizeof(buf), &transferred, TIMEOUT);
            
        if (r < 0) {
                fprintf(stderr, "Interrupt read error %d\n", r);
                return r;
        }

        for(i = 0;i < 5; i++) {
                if(i%8 == 0)
                        printf("\n");
                printf("%02x ",buf[i]);
          
        }

Is this correct way to get the data from the mouse?

Please suggest me how to go through, and some suggestions regarding this so that I can refer the same and get solved from this problem.
I'm awaiting for your valuable information.

Thank you
