Hi,

That is perhaps because they send less data than wMaxPacketSize.

Re: Read from bulk end point

2011-06-27 Thread Luca Pizzamiglio 

Hi,

the buffer size mitigates the pre-fetch, but could not remove it all... 
Setting 1 as buffer size, the pre-fetch is reduces as 3 wMaxPacketSize 
IN transaction on the bus, but could not avoid it.


There is a way to disable pre-fetch features? Or better, HPS could you 
point me where is implemented? (just to save time studying source code!)


Is the prefetch also enabled for Interrupt end point? maybe I could have 
push to correctly redesign this USB board...


thanks in advance!

Luca
