Hi,

In order to achieve a maximum continuous bandwidth for bulk transfers with the FX2LP, is it better to use one single endpoint, like EP2 with 512 byte or even 1024 byte quad buffered or is it better to use two endpoints, like EP2 and EP6, each with 512 byte quad buffered?

Transfers are asynchronous bulk transfers with multiple transfers queued in order to always have transfers ready.

Thanks!

Hi,

I think it will be better if you use 2 endpoints. You may also want to use enough buffering to suit bandwidth requirements and for handling the bursty nature of BULK endpoints.
