-	  USB mode switcher.
-	  Used to switch mode on multiple-function devices
+	  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 device's application mode. usb_modeswitch
+	  changes the mode of such devices from the initial power-up
+	  mode to the application mode. Specific configuration data
+	  for each device model is required.
+
+	  usb_modeswitch can be used with the usb_modeswitch_data
+	  package and udev for automatic mode switching when devices
+	  are connected.
+
+	  For more information search the Internet for "Virtual CD-ROM
+	  switching utility".
