xbox controller home button issue wont resolve

OK strange new development/observation

it appears if i plug the controller into the xbox via usb, than still the home button doesn't work, HOWEVER if i remove the batteries making the controller dependent on the xbox for power then the HOME BUTTON WORKS IMMEDIATELY! while plugged into the xbox
with a working home button if i put the batteries back into the controller, without hitting anything, the home button stops working again.

and remember the controller will turn the xbox on via home button even while not connected by USB...

what in the world is up with this controller?!

Tried a soft reset. Still not working :-(

Home button will turn the xbox on still but not register...

My last two thoughts..

A full factory reset...

Or

If there's a way to reset the controller firmware to factory and reinstall via USB....

The xbox tells me my controller is up to date... but I feel something went awry while updating firmware via bluetooth

Hi wwkingms,

Instead of a full factory, there is the option of a
soft reset which would keep your games and apps. That way it will be a short process when trying to test out the controller again on the console.

I hope this helps

i tried this out with much hope, i unlinked all 3 controllers from my account.

i removed the account, power cycled the xbox, when it turned back on clear of accounts the controller in question's home button still wasnt working :-\

i re-added my account anyway and changed my elite controller settings back to default everything on both profiles 1&2 just in case..

still nothing

if it matters when i first used the controller it updated without the USB cord whereas the other controllers required it if it matters.

ive check the firmware on it multiple times, plugged in and not.

i may try a factory wipe on the xbox.. i really dont want to go thru the warranty process

let me add that the controller will turn the xbox on via the home button..... which makes me think theres a software issue and that a new controller wont change anything...
