Hi gelenkeharald,
> debbuging is so much better with chipscope, why didn't I used it before? ;-)
Yes, but it's last fronteer, better to fix problems before it
>I remember that you already gave me the hint not to drive pktend. With chipscope I can see this must be the right way, because signals were send right. But in software there are still problems:
PKTEND it's good control, but you should know how it's work.

You can use any packet length less than 512 bytes (size of buffer and also limit for USB 2.0), but you should know that smaller packets = low latency but also low bandwidth usage, but bigger packets = high bandwidth but also high latency. If your project just collect data from ADCs and send it to PC and don't require fast response, so better choose big packet length (something around 500 bytes) and commit this packets by PKTEND signal.
I also know more ways to increase transfer speed but it's require FX2 firmware modifications.
> Where can I get this new project and driver, you mentioned?
It's ready, I just going to write some description and commit it to Github today evening (if I'll have time) or more possible tomorrow. Will write to this topic when done.
Regards
Alex
