Thanks
Yeah, you both are right, BUT

EWI USB is a Class-compliant, plug-and-play USB device
Then, I understand it is not necessary to have any driver.
Anyway, if necessary, where is the driver?
The only "file" or program that AKAI supply is the Aria Player.
Mario pointed me http://www.akaipro.com/ewiusb#
There is no driver there.
from that link:
FAQ
"Aria isn’t recognizing the EWI USB. Why?
EWI USB must be already connected to your computer’s USB port before your launch the Aria software. Restart Aria with EWI USB already plugged in.
If EWI USB is connected to your computer through a USB hub, try connecting it directly to one of your computer’s USB ports, then close and reopen Aria."
