-         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".
