My data is a big amount of data. "Jitter" is no problem. In reverse direction (PC -> LPC2148) there is almost no throughput required. There are various endpoints to choose from in LPC2148. Which one should i choose for my application ? If you have large amounts of data to send fast, bulk is the only good choice, and multiple endpoints won't help you. Double buffering will. DMA is unlikely to be necessary - you will probably be limited by the USB bandwidth.
