Thanks for this info. If we can't find a complete solution, I would also consider building an own device, but that is probably not what my customer (a software development company) want to do. However, if it was possible to find someone who builds a case with the keys and puts the controller inside, then ... maybe. I looked at a few examples and saw that using a serial line (RS232, as you mentioned, too) seems to be easy. However, that makes connecting the device more complicated. Do you know whether there are better ways to do it, maybe with a direct USB driver and an API that makes it more "direct" to use the key presses? (Sorry, if this is also in their examples, I only took a quick look and not an exhaustive investigation).
