Angel Guzman Maeso, it would be best not to conclude too much from similar problem, different hardware, as they can have differing root causes. Hence, for your hardware, and regression testing purposes, could you please test for this in Lucid via http://old- releases.ubuntu.com/releases/lucid/ and advise to the results?

It is mainly a bad detection as USB 1.0 instead of USB 2.0 in dmesg (check_highspeed is indeed bogus). Copy 20 GB takes days, instead of hours for this issue. The issue is mainly to copy or move files to a USB external storage device from the laptop or desktop.
