Hello,
I write a simple code to evaluate FX3 Super Speed capabilities for the project ahead. My Idea is to implement a one BULK out endpoint for video data a 2 Interrupt (IN + OUT) for control/status from sensor unit. Bulk endpoint behave as expected but interrupt one produce a message :<INTERRUPT IN transfer
INTERRUPT IN transfer failed with Error Code:997>
Where I can get info what that means. (All example projects with use of interrupt endpoints I already had examined)

Hi,
Please ensure that you are acking the data transfer done through the interupt endpoint. You can refer to the attached link to understand the similar error codes: https://msdn.microsoft.com/en-us/library/windows/desktop/ms681388(v=vs.85).aspx

For experiment I changed a interrupt endpoints to bulk one, (EP handlers are the same) and they work fine. Is there any special requirements for intrpt EP?
