My computer with vista x64 has about a 50% success rate at recognizing when I hook up my Moment via USB. I've installed the Samsung USB driver for mobile phones v220.127.116.11, as well as the Samsung New PC Studio software. I have debugging checked, tried different USB ports, etc, and the only thing that seems to work is power cycling the phone. Anyone have any ideas? android 2.1 p.s. I suspect this has something to do with the "Abnormal Disconnect" error I keep getting from pdanet.
