Subject: Re: [PATCH] Input: xpad - Update xboxone fw2015 init packet

I had this issue with official Microsoft Xbox One S Controler (model: 1708);
It might also be firmware version related as I recently updated my firmware
to the latest one but I'm not sure about that.

(also sorry for duplicate msgs that you might have received from me;
I'm new to lkml)
