Fast data transfer to PC

Hi all

I am looking into a way to send data fast from an AVR to a PC.
I had a look on the USB Scope project (http://yveslebrac.blogspot.com/2008/10/ ... alaxy.html), how ever need a faster data transfer.
There is an older discussion about this here: viewtopic.php?f=8&t=2036#p7264 , but doesn't give me much help.
What I am looking for is to get a data transfer of 1 kBps (1kBytes/sec), preferably even more
It would be good to have it in real time, but buffering/bulk send would also be ok.
Is that possible?
How would I have to do it?
Is there an example project/existing implementation?
I has a look in the examples/forum, but couldn't find anything like that.

Thank you for your advice.

The guy there writes that he was able to achieve 6kBps. According to viewtopic.php?f=8&t=19 the achieved maximum lies at almost 8kBps, so the 6kBps is not very bad. And there is code for this. So why does it not help you?

Thank you for your quick reply.

I saw those examples and now also tried to get them working.
How ever I can not even compile them. Size 2008 there seem to have al lot of changes happened in the API. Because of that I can not even get those examples working.

Despite of that, I figured out that I am only able to get the EasyLogger example to work. Any other newer or older example fails.
(This seems to be another problem, so I started another thread for it: viewtopic.php?f=8&t=5781)

If there is an easy way to get from the EasyLogger example to a high speed transfer that would be ok for me as well. But up to now I haven't yet fully understood what would have to be changed.
