From 332bb43f7c4baea2a0dce7ae2c078c55e14d37b5 Mon Sep 17 00:00:00 2001 From: Mike Lockwood Date: Wed, 16 May 2012 12:34:37 +0200 Subject: staging: usb: gadget: Add Configurable Composite Gadget driver The Configurable Gadget driver is a composite driver that allows userspace to change at runtime the list of functions enabled in its configuration and to configure these functions. It supports multiple functions: acm, rndis, and mass storage. It is usually controlled by a daemon that changes the configuration based on user settings. For example, rndis is enabled when the user enables sharing the phone data connection. As an example on how to use it, the following shell commands will make the gadget disconnect from the host and make it be re-enumerated as a composite with 1 rndis and 2 acm interfaces, and a different product id: echo 0 > /sys/class/ccg_usb/ccg0/enable echo rndis,acm > /sys/class/ccg_usb/ccg0/functions echo 2 > /sys/class/ccg_usb/ccg0/f_acm/instances echo -n 0x2d01 > /sys/module/g_ccg/parameters/idProduct echo 1 > /sys/class/ccg_usb/ccg0/enable The driver requires a gadget controller that supports software control of the D+ pullup and the controller driver must support disabling the pullup during composite_bind.
