when connecting usb drive i get a message to connect to fast usb port for better resuls
i have only 2 usb ports in my tecra M2 notebook.
why the fast connection message comes up if there is no such ports.
dmesg shows 4 usb ports initializing
can some one give me an idea how to access fast usb

you will need a machine built with usb 2.0 or 3.0 ports.
