    I added this line to the configuration file of the kernel

    device ehci

    rebooted the system and conected the usb disk and i get the same
    transfers speed
    1.00MB/s and in the /boot/kernel/ directory there is not ehci.ko file
    i have to add another line to the configuration file or it's compiled
    into the kernel

    You'll need device ehci in your kernel or module ehci.ko loaded. Even
    then, the reported speed is not always correct.
    To find out at what speed your device is running, try to transfer some
    large file with dd.

    HTH,

    Phil.
