[AT] Rivet how-to USB

[Larry D. Goss]

Most modern computers are not set up to allow for that.  There can only
be ONE Root USB controller in the system.  If you disable the one that
is built in on the mother board, then you have to be able to pick up all
its current ports.  That could include all the drives (hard, floppy, CD,
DVD, etc), card slots, keyboard, mouse, WI-FI, normal serial ports, game
controller slots, Ethernet...

There's a reason why late model computers do not have parallel ports --
all peripheral devices except the monitor are controlled through the
root USB.  If your computer is of such a vintage that its USB controller
is not integral with the mother board but rather that it is a plug-in
along with direct connections to other peripheral cards, then you stand
a chance of disabling it, but it isn't going to be a simple process.
The days of separate driver cards for every peripheral are gone.

Even on laptops which still have parallel ports on them, everything else
is running through the root USB controller.  You can disable some of the
existing ports, but disabling the whole controller is a different level
of manipulation.  You should be able to tell from the Device Manager
program whether the entire hierarchy of your computer runs through the
Root USB controller or not.

It is possible to get a add in card that has USB 2.0 on it and use that 
instead of the one on the motherboard.

You can probably disable the USB port in the BIOS and reclaim the 
resources it uses.
