Hack 8 Avoid the Legacy USB Option 
Save yourself from boot-up delays and Windows
device detection confusion.
The
Legacy USB setting tells the
BIOS and operating system to detect and enable USB keyboards and mice
in the absence of normal PS/2-port devices. Setting this parameter to
Yes, On, or Enabled is important and necessary if you have only a USB
keyboard and mouse and need to use them in non-Windows operating
systems, such as DOS, OS/2, some self-booting diagnostic/maintenance
programs, or the early stages of some Linux setups.
If this parameter is on or enabled and you use a normal PS/2-port
connected keyboard, with no USB-connected keyboard attached, Windows
95 and 98 may hang up looking for a USB keyboard that does not exist.
Disable or turn this setting off, or you could be fighting with the
system for a long time and it will probably win. Your system may also
boot up faster if it does not have to waste time looking for a
nonexistent device.
If you have a conventional or PS/2 keyboard and mouse, you never need
to enable this capability. For Windows
98SE,
Me, and
XP, which have native
USB support built in, you need to make sure this parameter is set to
No, Off, or Disabled as shown in Figure 1-10.

Legacy USB is one sadly misunderstood parameter. With USB 2.0 being
the current new USB standard, don't be misled into
thinking this has something to do with USB 2.0 ports supporting
"old" USB 1.1 devices—it does
not.
