I left my bionic USB cable at my parents house that is 2 hours way from mine. I tried to plug my bionic in and it wouldnt conenct to my pc. I was scratching my head for about 2 hours. I only have a generic usb cable and 3 different LG cables from previous phones. My droid bionic was not connecting via usb no matter what i did. I downloaded new drivers for two different computers. Tried vista vs windows 7 but still nothing. The phone would charge correctly but wasnt being noticed by the computers and the phone USB connection notification wouldn't appear. I tried removing battery, restarting the phone, removing and swapping the memory cards (even tho that shouldn't make a difference) and still nothing. Finnaly I found my old motorolla droid 1 cable and figured i would give it a shot and...TADA. It worked! what the hell is going on? I tested out my droid 1 and it connects via all 4 of the cables.
I wanted to put this in the forum in case others had this problem so it would come up in the search.
