Intel admits the problem is there but will not fix it and feels that well
written drivers will just ask the USB device for a resend of the missed
packet !!!??? They say that nobody will notice the missing packet
anyway??? I read this to mean "it is in the hardware now and there is no
soft/firmware patch possible." One hopes the 4th gen chips are better
designed. Thats what I am looking to buy. I don't have a USB2 device to
try though.

That is at least good news. I suspect a HW difference in the host off the
top of my head. I think the system pays more attention to them too.
