Hi all,

I have a PC that has a bios feature for USB Wake when in S4/S5 shutdown state.

My keyboards sucessfully wake the pc; however when using a Teensy 4.0 I notice that it would not work.

Digging deep using USB Tree Viewer I noticed that the Teensy 4.0 is missing specific supported power states under the Device Information.
It is missing D1, D2, Wake from D1, Wake from D2 capabilities.

Is there a straightforward way to enable this? It should have all power states a keyboard should have.

Please help me.
