ahh Happy day
I have spend some time, copying data from a working library to my libusb, I have check all include files and I have removed All code that werent used and now I can load the library :D
So what was the error..
In the library init function I try to open the usb device and that failes and never return (on my system)
well now I just have to figure out where to open the device and I'm back on track.
