Well, I just tried plugging the drive into one of the ports that come right from the motherboard and the diff relative to what I saw earlier is the following:

After the lines above, my khubd thread enters the D state.
If I try to issue a "cat /proc/bus/usb/devices" command, it hangs. BTW, I just received another line saying control timeout on ep0in. :-(
Is there anything else that I can do?
Thank you very much for your attention, Rogério Brito.
