Hi
We have a problem with our USB bulk device running on the M3 of the concerto controller. We can transmit thousands of telegrams to and from the PC, but after about half an hour, a telegram in the direction PC->controller is lost. After that, the software goes on normally, all further telegrams arrive on the controller. About every 10-40min one telegram is lost.
Is there a possibility that the ARM misses an USB interrupt somehow? Any hint where to look is appreciated.
Thanks and regards,
Daniel
