Djoen,
That is the case. I forgot about the silicon issue. However, my original response still stands. No matter what happens when Motorola fixes the silicon, you will still have to provide some software which makes the device work. There are no default descriptors or anything. You have to get that all sorted out yourself.
Logic can help you do this if you like. We have plenty of experience with USB and developing USB drivers for various platforms.
You should also check out
http://www.usb.org for information about the specific class of device you are creating.
