A curious situation cropped up yesterday. I usually connect my motorola razr xt 910 to the USB port in the car to play some music, to recharge and sorts. Yesterday my wife connected her Samsung Galaxy to the USB port to charge and it did charge. But once she disconnected her phone and i tried plugging in my phone, alas!, the USB port doesnt respond anymore. Usually when i connect my phone, the phone prompts to connect the device for charging, USB mass storage or windows media sync. Now, the phone doesnt prompt, neither is it getting charged through the USB. This is an unusual situation, so i connected Galaxy SII again and surprising it is charging. Has anyone here come across a situation like this? I am confused as the SII is working fine but my phone is not responding.
