问题
I am using Samsung Galaxy 3. I have turned on the debug option and have connected the phone via usb to ubuntu/windows but the phone is simply not recognized.
It was working perfectly fine i.e. recognized on ubuntu for me to work with Eclipse, until I decided to reboot the phone with usb still connected to the computer.
I have tried rebooting the phone multiple times and everytime, when I plug in the usb, it simply charges and no notification of usb connection ever shows up. What am I doing wrong here? Please help.

try using a different USB cable. I had a similar issue where my phone had previously connected just fine, but months later it wasn't recognized...
turns out the cable I was using was a "charging only" cable and did not transmit data.
