This is quite strange, since I never had to deal with it before. I just got an Iomega 40 GB External HDD and and ARCHOS 20 GB MP3 player both of which support USB 2.0. My motherboard is an ASUS A7V33 which supports USB 2.0. (More Info on the mobo here: http://usa.asus.com/prog/spec.asp?m=A7V333&langs=09)

Now here's the issue, whenever I plug in either device (I've tried all 4 ports), WinXP Pro says "A high speed USB device plugged into a non-high speed USB port/hub" (or something to that effect). But it doesn't make any sense since both devices work fine on my USB 2.0 PC Card in my laptop. I can use them on my desktop, but without USB 2.0 capabilities. I have downloaded the latest Windows Updates, and I have the latest non-BETA BIOS for my mobo.

So what could be wrong? I don't see if there's anything I need to do with my BIOS since the ports work fine at USB 1.1, but they don't seem to work at USB 2.0.

Any ideas?
