Hello
this is a good question.
for some notebook , such device is available even before April.
infact at this page you can find the driver and the date is March 1st.

fro my understanding its a new device used by some HP applications such as HP Velocity , HP Hotkeys, plus other that actually I don't know. I'll find more information in the future , I'll update this post.
In order to stay updated with some HP utility , I guess it's better to have that device enale in the BIOS , then install the driver, so your computer will be able to run correctly newer version of HP software.
Bye
