Exchanged keyboard from UK layout to German (hardware)
MacBook Pro 15" Retina A1398
Does changing UK keyboard for German one require me to update or flash some kind of firmware or update software?
I have replaced keyboard from UK to German and now I have information that something is draining too much power and the USB has to be disabled.
El Captain is giving me kernel crash pointing towards USB xhci and not booting,
Updating to High Sierra gives me sleep/wakeup failure pointing towards USB and two dead USB ports (but SD card reader and HDMI working just fine) and info about drawing too much power, downgrading to Mountain Lion makes one of USB (left side) working but I think as USB 2.0 and second one dead but no sleep/wake problems whatsoever, and upgrading to Yosemite leaves computer with same problem as in Mountain Lion. But beside working good with one USB port.
I'm not sure if changing keyboard to different language should be made with some software servicing?
Sorry I have forgot to add that I have also done SMC and NVRAM resets and hardware test showing all good.

Can you clarify which A1398 model you have. Review this listing: 15" MacBook Pro's A1398 models

How did you replace the keyboard? Did you switch out the uppercase, or did you completely take the system apart and replace the keyboard alone?
Did you have any problems with your original keyboard that you had to go this far instead of just popping off the keycaps.

Dan thank You for response. I have taken system apart and exchanged keyboard.
My model is MacBook Pro 15" 2.7 GHz i7 Retina (2012)
I had no problems with keyboard whatsoever, just felt that whole new keyboard will be more solid than popping buttons .
However I remember that I was having similar problem when I was installing el captain years ago for a first time when original keyboard was there.
As far as I can tell there was no problem with installing keyboard and as I have said it is working fine when OS X is working.
