Ive had this lg optimus v almost 3 months. Connected to my computer with no problems... Plugged it in today & all it does is charge it. Device manager does not reconize it. So far I tried 2 computers. Tried all usb ports. Tried 2 data cords. Pulled battery out, held power button down & even reset the phone to factory settings.. Has anybody else had this problem & fixed it? Any suggestions I have not done to fix this?
