+	  Some models of some USB devices such as modems and Wifi adapters
+	  power-up in mass storage mode to provide access to drivers for the

+	  devices from the initial power-up mode to the application mode.
+	  Specific configuration data for each device model is required.

+	  for automatic mode switching when devices are connected.
