Thanks for your answer.
I made a test & I confirm what you said.
I am able to use IN on al devices in the same millisecond.
But IN + OUT on the same device must be done on 2 ms.

If the IN/OUT takes 2 ms, that is probably something that is due to
suboptimal driver, application or host controller implementation. As
far as I know, there's nothing in the USB standard that would prevent
this all being done in the same 1 ms frame.
