I seem to be having an issue connecting my phone to my computer. When i plug the phone into the computer, I have windows 7 by the way, it will make the ding that it has connected but then five seconds later it makes the disconnect sound. It will keep on dinging again and again until i unplug my phone from the computer. For the Galaxy S3 its model number is Sch-I535, I know the verizon one. For some information about the settings I have usb debugging enabled and I have "allow mock locations" enabled too. Also the phone is rooted. Any help would be appreciated and if you guys need more information just ask.
