USB disk identification failure

OK someone suggested I turn off my phone , left it off for 10 minutes got in the car turned it on , plugged it in , nothing happened. Drove about 10 mins, got out , went to a shop. Got back in plugged in the phone ,started the car and 2 mins later everything is perfect.

I have started having this issue USB identification error recently a few months. did the factory reset and being to garage to update software and the problem came back after 24 hours. the V12 battery is draining if the car isnt used every day. after jumping the v12 battery the radio resets but three days later back to usb ID failure and same problems. I haven't plugged any phone into the car in weeks now so its going to the garage again today.
