USB2

Hi

I'm having some problems with USB2.
According to ASUS specs, my pc (A2526KUH) has 5xUSB2 ports. 
But lspci says the following:
0000:00:02.0 USB Controller: nVidia Corporation nForce3 USB 1.1 (rev a5)
0000:00:02.1 USB Controller: nVidia Corporation nForce3 USB 1.1 (rev a5)
0000:00:02.2 USB Controller: nVidia Corporation nForce3 USB 2.0 (rev a2)

Anyway when I insert my Packard Bell 1Gb mp3 player it's used by the
OHCI driver, instead of the (also loaded) ehci! I tried all the five
ports, all the same!
I tried also an external USB2 HDD but does the same.

This is the output of messages

After these message I tried copying 139Mb: it took 2m30 -> 1Mb/s (fullspeed)

any ideas?
thanks
