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!
