Yes, that's it.

Ok i'll do that. Since it's the device that's reporting t's capabilities 
directly instead of the driver knowing about different device versions i'd
like to get this clarified before i distribute the firmware and driver.

I transformed my old lcd2usb into a test device. But since i don't need
such a "big" cpu as the atmega8 i have started to build a smaller version
based upon the attiny45 (hence the name i2c-tiny-usb). Once that
one is working i'll put a first version of the whole setup online.
