I know that certain AMD USB controllers perform less with the new USB stack,
but I've not been able to track down the issue.
Yes, I have AMD platform (motherboard ASUS A8N-VM-CSM)
Can you try another PC having another CPU brand?
Yes, I have already posted the result - 22 Mb/sec, much better

I think the reduced performance can be explained by a clamp on the interrupt
rate around 1000 interrupts per second instead of 8000. Maybe someone has an
explanation for this?
The EHCI is being programmed to interrupt at 125us intervals, but there seems
to be limits other places.
