// will get all entries of all USB devices, the USB host controllers, the USB Root hubs , hubs and usb devices. 
// The results that are located at "USB\VID_xxx&PID_yyyy\zzzz"
// it may happen that you have more than one USB device with the same VID and PID on the system. 
// Therfore you must also check for the serial# (the zzzz in the bold text). A USB device is only unique with VID+PID+seial#.
