So I've seen people ask a similar question, but none of the results seem to apply to my problem. I have a Samsung Fascinate Galaxy S, I've only had it for about a week and a half now. The first time I tried running PDAnet, it worked awesome... for about twenty minutes. After only twenty minutes of usage, I got the error message that the disk had been ejected improperly, and my internet connection was severed. I don't understand what happened. Nothing was touched on my phone or the computer to make it seem not connected. The USB cable was still plugged into my phone, but upon further investigation, I found out that my USB Debugging had turned off for some unknown reason. It's been a week since I discovered this problem and I've tried a hard reset, a regular reset, I've tried fussing with the wifi and blue tooth, and I've even tried letting the mass storage program run, but it keeps disconnecting. What am I supposed to do? Having free tethering on this phone is my only option to have internet. Help me please!
