I have understand this.
But how could you explain that for a simple USB keyboard or mousse, the system desn't install alone....The only thing I do is clicking "next" and it installs its own drivers without any CD.
Another example, once I pluged the device in an usb port and installed driver, if I unplug it and plug it again in the same USB port, no problem.
But if I change the USB port, It asks me again to install driver.
