I'm having some problems when trying to connect my Samsung Infuse 4G to my PC. Everytime I plug the USB to the computer it does not recognize the device. Meanwhile when I look at the cellphone it also does not show that it there is an USB connection, even though it starts charging. So summarizing: I connect my phone to my PC, it starts charging but both the phone and the computer do not recognize the USB connection, so I can't use it for some functions as Mass Storage. In the phone screen it wont even open that three options to chose what kind of USB connection you want. I already tried changing my USB cable, turning on USB debugging but it also did not work. Any one has a clue about what might it be? So far I think it could be some problem in the phone's USB plug, although it still works for charging the device.
