Why do you think that Linux didn't detect the device as USB 2.0? What does /proc/bus/usb/devices say about it? Maybe you really mean that the device _is_ recognized as USB 2.0, but it _runs_ only at USB 1.1 full speed (12 Mb/s) instead of USB 2.0 high speed (480 Mb/s). According to your lspci output, all three of the USB controllers on your computer are USB 1.1. So of course they won't be able to operate at USB 2.0's high speed.
