Conformance tests should consist of a driver and a program to load 
it. I do not know other method to call functions from ntoskrnl.exe and 
usbd.sys on Windows. But I have a problem with building drivers with MinGW. I 
was able to create a driver which is loading on Wine with manual editing of 
PE header but it does not work on Windows and I do not understand what should 
change to fix this. Did somebody build NT drivers with MinGW?
