During connecting device USB logger shows two devices

Thanks for reply,

yes, i resolved that problem. I've corrected some stack functions couse of hwr problems which i found in 'Silicon Anomaly List'. But i've got another problem now (i think there is no neet to start another post ). During conecting device USB logger shows two devices. Fist is Unknown Device(1) and second is (correct) MyDevice(2) (see attachment). After plug, host sends some data to device 1 and then starts enumeration of proper device. Thats happen every time. I think that is related with some time periods of device respond, am i right? but i do not know where to look for errors cause communicationns works correct. Any ideas? Thanks for any help.
