Well I did a

modprobe -rv ehci-hcd
modprobe -rv ohci-hcd

The USB keyboard stopped working after I removed ohci-hcd.

I unplugged and replugged the USB M/K adapter and nothing happene.  No 
mouse, no keyboard (of course notebook mouse/pointer continued to 
work).  Then I did a:

modprobe -v ohci-hcd

And the usb keyboard started up,  but not the mouse.

gpm restart did nothing.

Well, it is time to move my notebook.  Next local only has a usb mouse, 
no kvm, no external keyboard...
