USB Controller/HUB

Ran into a new one (unrelated to new 8/core build). Mouse went
haywire in Windows. Checked mouse, its USB connections (cleaned usb
ports), restored OS serval times, reset BIOS. Lots of power on/offs.

Still a no go. Mad mouse on the loose, totally beserk, dangerously
so, with Windows OS repeatedly (after all above) randomly interpreting
clicks, drags -- initiating and interjecting them on its own.
Resultant actions/havoc generally contained over a matter beneath the
pointer - e.g. whether a program, severe, or desktop, less severe.

I unistalled viz Device Manager a single instance of a PCI to USB
Controller, which immediately caused an OS re-detection and
reinstallation/initialization.

Which fixed "the problem".

And that's as in still fixed when, immediately afterwards, I again
repeated a binary/sector OS rewrite/restore, which brought back a very
same older instance of an OS with the erractic mouse behavior present.

This is as if the USB controller was in some sort of an individual
CMOS state, messed up until the abovementioned OS redetection "fix",
or in other words operating independently of both complete power
hardware & BIOS resets, and then altogther indepently functioning
apart from the OS supposed fix, afterwards and once the OS was
entirely rewritten.

USB and USB hub problems, they sure can be some of the worst.
