Yes - I did … but cannot say if it changed anything since, as mentioned above, everything is working fine for the last 24 hours (keyboard able to operate in boot menu etc.) As mentioned above it came back by itself, after multiple un/replugging into various ports, as well as the Wacom, which was also
not recognized. So-at the time when re-installing all USSB controllers it was already working.
I checked sfc...all good, checked by going into save mode-... keyboard works.
I have though an error code 455 ESENT...??
But that lower USB port-bank on the computer is where most problems occurred.
(devices there are recognized … then all of a sudden not …)
It's the sporadic / unpredictable nature of the problem that makes it hard to pinpoint
Any results from the diagnostic tool?
Thanks
