Hi, I hope this one gets through correctly.
I know it's know what optimal as it should apply to the current 'work' but I had some issues doing that and no time to find out what the issue is. If possible, please apply to cdc-at91 If not, than I will be reviewing it in a couple of months I guess. The code I send is compiling in cdc-at91 branch and working well for my board and should work as well for at91_udc boards I think. If anyone likes to help out on this, please go ahead ! btw, thanks again to all people who already helped. I perhaps have a few hours left this week to work on this, but no more than that. I hope for someone to take over from me at this point.
