[Libusb-devel] libusb_get_device_descriptor( devh->dev, &desc ) reports compile error: dereferencing pointer to incomplete type

[Liu W. <li...@su...>]

You'd be appreciated pulling me up from the following.

libusb_get_device_descriptor( devh->dev, &desc ) reports compile error: dereferencing pointer to incomplete type


int sl_init( void )
{
	int r = 1;
	struct libusb_device_descriptor desc;

	r = libusb_init( NULL );
	if (r < 0) {
		fprintf( stderr, "failed to initialise libusb\n" );
		return r;
	}
	
	r = find_smclcd( );
	if ( r < 0 ) {
		fprintf( stderr, "Could not find/open device\n" );
		return r;
	}

	r = libusb_get_device_descriptor( devh->dev, &desc );////// pull me up here please.
	if (r < 0) {
		printf( "failed to get device descriptor" );
		return r;
	}

	r = libusb_detach_kernel_driver( devh, 0 );
	if ( r < 0 ) {
		fprintf( stderr, "libsub_detach_kernel_driver %d %s\n", r, strerror(-r) );
		return r;
	}

	r = libusb_claim_interface( devh, 0 );
	if ( r < 0 ) {
		fprintf( stderr, "usb_claim_interface error %d %s\n", r, strerror(-r) );
		return r;
	}
	printf("claimed interface\n");
	

	r = 0; 
	return r;
}

I totally understand your position.

That would be very good. Thanks.
