Hi,

 

I need to send some stuff on isochronous endpoint to host from coldfire MCF52259.

 

My question is that do we use both odd and even buffers for isochronous. As per USB specification, we need to send the data only on DATA0.

 

Also, if we do use both odd and even buffers, then what will be the first buffer. Is it EVEN?

 

Thanks in advance.

 

Regards.

Basically, I can get the data on EVEN buffer descriptor but unable to get on ODD buffer descriptor.

Any help will be highly appreciated.
