I'm using the HID Utilities provided by Apple. This works fine, but while scanning device list, I got 2 keyboards : The one that
I have connected, and another one called "Generic Keyboard". This Generic Keyboard, does not disappear when I unplug my keyboard

Is it a normal behavior to have a keyboard detected even when there no one ?

And where can I find a list of registered vendor/product ID for HID devices ?

Thanks for your help,
