It's not needed for normal support, no. It's quite useful for debugging
and adding support for new devices, though.

You can compare it a bit with USB Raw Gadget or HIDRAW (except that we
don't want anyone writing user-space drivers against that interface),
i.e. it provides a direct channel from user-space to the EC. Setting
this option to M provides a module that needs to be loaded in explicitly
when someone wants to use it.

I've added it to the list because other distros (Ubuntu, Arch) have
enabled it. Feel free to keep it disabled.

Regards,
Max
