Hi USB list,
I've a little problem, but I'm not able to find a solution...
I've a generic custom USB device with several end points.
One of them (a bulk one) is read periodically (polled, 64 byte) every
second. There was some time inconsistencies, so I checked the USB
traffic with a sniffer, an

Hi,
the buffer size mitigates the pre-fetch, but could not remove it all...
