Thanks for your response, that helped a lot!

If you choose the hardware way, remember that you need to fill in the complete packet headers, including Ethernet, IP and UPD.

OK.

I am sorry if I am changing the subject/topic so abruptly, but my next question is:

Do you think it would be a more simple and faster solution to use USB instead for communicating with the PC?

The downsides to USB are that it has limited connectivity (length, point-to-point) and you have to write everything pretty much yourself. You don't get to take advantage of the existing software and hardware that are built around TCP/IP. Ethernet is nice because you don't have to write any of the low-level stuff.

So here we can compare now: What is more difficult: Generating the Ethernet frames in hardware (and fill in all these headers) or using USB and writing everything pretty much myself?
