I've searched this forum and Google for about 3 hours tonight and I can not for the life of me figure out what the problem is. I got my Droid a week ago and I connected it via USB the day I got it and my PC (Win 7 x64) recognized it and I was able to transfer a file over. I had not tried to connect my Droid to my pc again until tonight when I wanted to try out PDANet. I connected it, dragged the notification bar down, selected the usb storage option and then selected mount. My computer just will not recognize it. I have power cycled both devices, formatted the SD card inside the phone and also under Win 7 by taking the card out and putting it in a card reader. I've also tried connecting while in USB debug mode. Sometimes it "works," and it will show up in explorer, but when I try to access it gives me an error telling me to insert the disc. Is there some driver I'm missing or something? The funny thing is, it works perfectly under OS X. I know I could just take the card out and use a card reader every time I want to transfer files, but that's kind of a pain and if I can just do it via usb I'd much rather do that. Any help is appreciated.
