I assume that SIE of FX2LP responds immediately to EP1IN bulk transaction without NACK one or two times soon after "SET_FEATURE(to endpoint81) REQUEST" although firmware does not arm the EP1IN yet.

EP1IN is armed in accordance with timer2 expilation by polling TF2. SIE seems to ignore these intervals. Is my opinion right ?

Hello,

There may be my firmware issue (handling of timer2 function).So I would reserve judgment for the time being.

This issue will be fixed If I can cancel (disarm) previously (re)armed EP1IN.

Best Regards,

Please note that there was an error in the post where the "REQUEST"was incorrectly given as "SET_FEATURE", where it should have been "CLEAR_FEATURE".

Hello,

Please clarify my understanding of your query- are you seeing data on the host after the Clear Feature request on the endpoint clears STALL condition? Is this happening even in the interval the endpoint is not armed?
