Have you tried plugging the phone into different computers? > I send in attachment the new trace of usbmon, > thank you again for the help, The trace shows what you described: The phone worked until you switched it into storage mode. Then it disconnected, reconnected, and did not work again. Maybe it will work better if you put the phone into storage mode, then turn it off and on again.
