Eventually I've managed to talk with a HID (external power switch) but
the first parameter for CreateFile( ... ) is rather strange to get.
I have the following code:

HANDLE hdriver;
 
hdriver=CreateFile("\\\\.\\HID#Vid_0000&Pid_003f#6&267ac536&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}", 

                   GENERIC_WRITE,
                   FILE_SHARE_WRITE,
                   NULL,
                   OPEN_EXISTING,
                   FILE_ATTRIBUTE_NORMAL,
                   NULL );

which operates very well. I can switch LiisaPowerSwitch on and off.
Is there an appropriate way to get the first parameter a bit simpler 
than by cut&paste from the registry?
