Help on using this USB component

Posted by Caramia p12316 on April 05, 2005:

Hello
In my program i must control if a device is connected to USB port.
I discoverd on Torry's this component:

htp://www.swissdelphicenter.ch/torry/showcode.php?id=2211

but i have no idea how i can use it. I tried to install (Component/InstallComponent... NewPackage). All was ok and the new package is now added to all other packages, LibraryPath has been updated but no component was added to palette.
I don't understand how to use it and how to built it inside my program. What function/procedure resturns information about the USB port?
Can you help me please?
Thanks
