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.
