I have done so with MSVC++ like this

Code: 

extern "C"
{
#include "opendevice.h"
}

usb_dev_handle *m_Handle = NULL;

Where opendevice.h & .c are taken directly from the v-usb custom class example. The device is initialized like so

Code: 

   static char vendor[]  = "Usb Vendor Name";
   static char product[] = "Usb Device Name";
   usb_init();
   m_Init = ( usbOpenDevice( &m_Handle,
      USB_VENDOR_ID, vendor,
      USB_DEVICE_ID, product,
      NULL, NULL, NULL ) == 0 );


It's been a while since I did this so I may have missed something but hopefully you get the idea.

When I compile hiddata commandline as single file (hidtool.c) I link libraries libsetupapi.a and libhid.a and it compliles without any problem.
But when I create a empty project and add hidtool.c to it, it seems that it cant find these libraries because some linker errors happen. I was trying to link them either by Tools -> Compiler Options ->Add these commands to linker command line or by Project Options->Additional Command Line Options but it doesnt work.

Is there any solution to that problem?

Code:
