I'm not sure I understand what you said.
It sure sounds like leaving Legacy enabled would cover ALL bases, and if
that's the case, I wonder why there's even an option to disable the Legacy?
Hmmm, but that sounds too simplistic.
So I guess one might "assume" that it's normally preferable not to select it
(Legacy), unless you know you are going to need it - for reasons that are
still unclear.

Sometimes the legacy thing is a problem for the keyboard on some older

motherboards I'm talking about can't find a USB keyboard with legacy
disabled. And, you can't get to the bios to change it as the bios can't
find a keyboard. All the ones I've found like this also had a PS/2 port
for
a keyboard. So, in this case, you might as well stick with a PS/2
keyboard.
XP seems to know what to do with legacy and USB, and uses the USB
communication version hardware. Motherboard mounted that is.

So it would be best to leave that option on, in case you ever wanted it,
for such cases? Is there any drawback to leaving that legacy enabled?

In a nutshell, legacy is a reroute of USB keyboard and/or mouse to allow
an
OS to use same. XP does not need legacy support of a USB keyboard or
mouse.
An example of where legacy support is required of a USB keyboard is real
mode msdos. And, a USB mouse would be addressed as a standard PS/2
mouse
in msdos using its mouse driver with legacy support enabled.

I'm having some problems with my PC. I went into BIOS and one of the
options
is to enable, disable USB Legacy. What is the purpose of USB Legacy?
Also
what will the result be if I leave it disabled?
Any help would be greatly appreciated!
Thanks, attilathehun1
