USB behavior

I have an ASUS P4P800 Deluxe motherboard, which has 4
onboard USB 2.0 capable ports, and another 4 that can be
broken out into a drivebay (which I don't have installed).

The 4 onboard ports work mostly as expected with one
major flaw: Devices have to be plugged into the ports
when the machine boots to be recognized. If I plug
something into the port after booting, the ports are
dead, and nothing gets recognized. If I plug a self-
powered USB hub into the port at boot time, all ports on
the hub are fine too.

I tried to install the USB drivers from the mboard CD,
but it says that I don't need to install because the
drivers are native in XP (Windows XP Pro is installed).

Anyone seen this behavior? How do I tell if USB 2.0
capable drivers are installed in XP?

Thanks!
 
Have same MB, no problem with USB 2.0 either with connected at start-up
(several devices, powered hub) or with devices plugged in during XP session.

Look for an entry under Universal Serial Bus that mentions an "Standard
Enhanced PCI to USB Controler". The enhanced part is the key - XP talk for
USB 2.0!

Hope this helps!
