ReactOS' setupapi.dll doesn't forward CM_* functions to cfgmgr32.dll. 
These functions are implemented in setupapi.dll and cfgmgr32.dll 
forwards them to setupapi.dll. Just like WinXP does.

It looks like our CM_Locate_DevNodeA in setupapi.dll is being called.

All CM_* functions used by usbview.exe are not implemented properly but 
I'm curremtly working on it. The required functionality in ntoskrnl.exe 
is implemented but higher levels in setupapi.dll and umpnpmgr.exe, like 
RPC-Stubs and String Tables are still missing. I think I'll need another 
3 or 4 weekends to get this working.
