Maybe not the right place here, but:
I have a fingerprint-sensor attached to a Teensy 3.2.. When i touch it with the right finger, it sends a string (a password) as a keyboard to the PC.. That works great,
In my devicemanager is see two keyboard ( my actual keyboard and my teensy, simulating a keyboard), but there is a difference: when i look at the properties, the keyboard has a energy-tab where i can switch on or off the ability to wake the computer from hibernate.. The Teensy-keyboard lacks this tab..
When i look further in the Details>Energy i see there is no PDCAP_WAKE_FROM_D2_SUPPORTED....
I guess that somewher in the compilation and uploading this flags are defined... Where is that and is there a way to change that, so my Teensy becomes able to wake my PC....
I don't know if it will help but I have read that there are two types of USB keyboard protocol: "boot protocol" and "report protocol".
This page discusses some of the differences:

thanks... read it, but this is what i already knew and doesn't lead to what i want. this is about two layers higher, maybe.. anyway.....
