Hi Mel,

- From what I see, it doesn't seem like you have 2.0, but try the
following to be sure:

# dmesg | grep ehci
# lspci -v | less

If dmesg doesn't say that you are loading the "ehci_hcd" module (or
something similar if you are using older 2.4 kernels), then try the
lspci -v command, and see what it says about your USB controller. It
should say either USB 2.0 or tell you to use the EHCI module with it.
For example, this is what lspci -v gives me on my Asus P4P800 (relevant
output shown):

00:1d.7 USB Controller: Intel Corp. 82801EB USB2 (rev 02) (prog-if 20
[EHCI])

Finally, you could check your BIOS and look for a setting to
enable/disable the USB2.0 controller. I don't know where it is in your
BIOS setup though, so check your manual.

I hope this helps.
