+# Following are the parameters required for usb functionality. They provide configurable options like
+# product_id/vendor id and allows specifying required functions:
+#
+# Required parameters:
+#
+# /sys/class/android_usb/android0/enable: Enables/disables usb composition
+# Value: 0 (disable), 1 (enable)
+#
+# /sys/class/android_usb/android0/idVendor: Stores Vendor ID
+# Value: 05c6 (Vendor id for Qualcomm Inc)
+#
+# /sys/class/android_usb/android0/idProduct: Stores Product id corresponding to usb composition
+# Value: 0x9xxx for composite interface, 0xFxxx for single interface
+#
+# /sys/class/android_usb/android0/f_diag/clients: Stores name of clients representing a diag interface.
+# Value: Passed one per interface. e.g. diag[,diag_mdm, diag_qsc, diag_mdm2]
+#
+# /sys/class/android_usb/android0/functions: Stores name of the function drivers used in usb composition.
+# Value: Passed one per function driver. e.g. diag[,adb]
+#
+#Optional parameters:
+#
+# /sys/class/android_usb/android0/f_serial/transports: Stores type of underlying transports used to
+# communicate to serial interface.
+# Value: Passed one per interface. One value represents control and data transport together.
+# e.g. smd[,sdio,tty,hsic]
+# Only required if serial interface is present.
+#
+# /sys/class/android_usb/android0/f_serial/transport_names: Stores name of the underlying transports
+# used to communicate to serial interface. This is used to distinguish between more than one interface
+# using same transport type.
+# Value: Passed one per interface. One value represents control and data transport together.
+# e.g. serial_hsic[,serial_hsusb]
+# Only required for transport type hsic, optional for other transport types.
+#
+# /sys/class/android_usb/android0/f_rmnet/transports: Stores type of underlying transports used to
+# communicate to rmnet interface.
+# Value: Passed two per interface as control, data transport type pair.
+# e.g. smd,bam[,hsuart,hsuart]
+# Only required if rmnet interface is present.
+#
+# /sys/class/android_usb/android0/f_rmnet/transport_names: Stores name of the underlying transports
+# used to communicate to rmnet interface. This is used to distinguish between more than one interface
+# using same transport type.
+# Value: Passed one per interface. One value represents control and data transport together.
+# e.g. rmnet_hsic[,rmnet_hsusb]
+# Only required for transport type hsic, optional for other transport types.
