Any help appreciated?

Due to some reason sometimes adb gets disconnected, so in that case you have to reset the adb.

Go to DDMS->Devices and you will see reset adb option in View Menu besides Screen Capture option.

Another way to restart the adb is through terminal or command line. Depending on if you have adb in your path just type:

$ adb kill-server

$ adb start-server

If adb is not in your path then:

$ path-to-sdk/platform-tools/adb kill-server

$ path-to-sdk/platform-tools/adb start-server

Hope this helps!

Loose connection of the cable connecting the device i hope.

Go to DDMS->Devices and you will see restart adb option in View Menu besides Screen Capture option.

In preferences change the android/DDMS log settings from "error" to "debug". After this you should be able to use the Reset adb option.
