I was not able to find anything specific only for "USB Connected", but there are several broadcast actions that may be of interest in this case, depending on what you are trying to do:

  • ACTION_MEDIA_SHARED: External media is disconnected because it is shared with USB mass storage.
  • ACTION_UMS_CONNECTED: The device has switched to USB Mass Storage mode. This is mainly used for the USB settings panel.
  • ACTION_UMS_DISCONNECTED: The device has exited USB Mass Storage mode. This is mainly used for the USB settings panel.
