I am trying to mount my Galaxy S2 on Debian Squeeze laptop. I turned off USB debugging and then in Wireless & n/w > USB Util I tapped connect connect storage to PC, it asks me to connect a USB cable, as soon as I connect the USB cable the pop goes away and my phone starts charging but I don't see my phone mounted in my laptop. I did `lsusb` and don't see any Samsung device connected. Then I decided to turn on USB debugging and did `lsusb` again but no luck. What could be wrong?
