I have a Samsung SCH A930 CDMA cell phone with a USB cable and I have installed the driver software from Samsung’s website in my PC. Then I tried to download some music (in WMA format) to my cell phone. When I connected my phone to PC, I got a ‘connection failure’ message in the phone and ‘the device is unplugged’ message in the PC. Also, the USB cable is actually for SCH A870. How can I download USB driver software to my Samsung SCH A930 CDMA cell phone? I would really appreciate your useful assistance. I hope to hear at the earliest from you guys out there. Thanks.
