Thanks for the in-depth report.  The keyboard is DURGOD all-usb
gaming one that cost me about 5 times a cheapo and I would
have been better off with the cheapo. I can duplicate the problem
at will and either it or the mobo is a lemmon. The problem seems
to be at its worse early in the boot, like when I would wanna hit
"Del" to get to the bios, or very soon after that to arrow-key my
way to a boot menu entry. The problem ceases to exist if I launch
with the cheapo and then optionally swap in the DURGOD. There is
NO BOUBT, for some reason the cheapo does not have a detection
issue the DURGOD does. It could be a matter of the latter needing
just a little more time to be detected, beats me :)

Anyway that's anoter part of the mystery down for a total of two
