Dear all


I encounted a problem with MX53 usb device mode.

I set the MX53 to bulk only devce with my self firmware code,

and I initial enpoint 1 to "Bulk IN" and enpoint 2 to "Bulk OUT".


I had got the "set configuration 1" command  from endpoint 0.

But I don't know how to get OUT command from endpoint 2, like to get "setup command" from endpoint 0,

Then I don't know when to prime the data from Host? There is no any NAK and Complete status from endpoint 1 & 2.


Thanks for your help!
