Hello I have a motorola v3x, i got a headphone adaptor(mini usb-3.5 headphone), I have had a problem with it, one minute it works fine then I unplug it, turn my phone off and when i turn it back on the cable doesnt work, i check the usb connection is on data conection and it makes no difference. I leave if overnight and the next day it works fine, do you know if it is the phone or my adaptor which is faulty?, do you know what I should do? Help will be appresited.
