+
+* Overview
+
+The Multifunction Composite Gadget (or g_multi) is a customisable
+composite gadget that makes extensive use of the composite framework
+to provide a... multifunction gadget.
+
+In it's standard configuration it provides a single USB configuration
+with RNDIS[1] (that is Ethernet), USB CDC[2] ACM (that is serial) and
+USB Mass Storage functions.
+
+Each function can be disabled via a Kconfig option. There's also
+a CDC ECM (Ethernet) function which can be turned on. If, however,
+CDC ECM and RNDIS are enabled the gadget will have two configurations
+-- one with RNDIS and another with CDC ECM[3].
+
+Please not, however, that if you use non-standard configuration you
+may need to change vendor and/or product ID.
+
+* Linux host drivers
+
+Since the gadget uses standard composite framework and appears as such
+to Linux host it does not need any additional drivers on Linux host
+side. All the functions are handled by respective drivers designed
+for them.
+
+This is also true for two configuration set-up with RNDIS
+configuration being the first one. Linux host will use the second
+configuration with CDC ECM which should work better under Linux.
+
+* Windows host drivers
+
+For the gadget two work under Windown two conditions have to be met:
+
+** Detecting as composite gadget
+
+First of all, Windows need to detect the gadget as an USB composite
+gadget (Microsoft calls it USB Generic Parent Driver[4]). This on its
+own have some conditions[5]. The good news is that you don't have to
+worry about most of them.
+
+The only thing to worry is that Windows won't use its USB Generic
+Parent Driver unless the gadget has a single configuration so a dual
+RNDIS and CDC ECM gadget won't work unless you create an INF. And of
+course, if you do submit it!
+
+** Attaching drivers for each function
+
+The other, trickier thing is making Windows attach drivers to each
+individual function.
+
+For mass storage it is trivial since Windows detect it's an USB Mass
+Storage class and selects appropriate driver.
+
+Things are harder with RDNIS and CDC ACM.
+
+*** RNDIS
+
+To make Windows select RNDIS drivers for the first function in the
+gadget, one needs to use the [[file:gadget_multi_rndis.inf]] file
+provided with this document. It "attaches" Window's RNDIS driver to
+the first interface of the gadget.
+
+*** CDC ACM
+
+Similarly, [[file:gadget_multi_serial.inf]] is provided for CDC ACM.
+Note, however that it also requires an usbser.sys file which can be
+extracted form Windows XP SP3 cab files.
+
+It is important to note that this works only with this particular
+version of the usbser.sys file and not the other versions that can be
+found on the Internet.
+
+*** Customising the gadget
+
+It is important to note, that after customising g_multi interface
+numbers change and so provided INF files will most likely stop working
+due to interface number mismatch.
+
+This also means, that after changing the set of functions available in
+g_multi one should change gadget's vendor and/or product ID so there
+will be no collision with other customised gadgets or the original
+gadget.
+
+*** Improvements in INF files
+
+It needs to be noted that we are not Windows driver experts and as
+such we do not claim that provided INF files are the flawless or that
+they will work on each and every Windows versions (they were tested on
+Windows XP SP3 only).
+
+The bottom line is, if you can improve the INF files, please do and
+share the results. :)
+
+* Other systems
+
+At this moment, drivers for any other systems have not been tested.
+Knowing how MacOS is based on BSD and BSD is an Open Source it is
+believed that (read: "I have no idea whether"), unlike under Windows,
+it should work out-of-the-box.
+
+For more exotic systems I have even less to say...
+
+Any testing and drivers *are* *welcome*!
+
+* Authors
+
+This document has been written by Michal Nazarewicz
+([[mailto:m.nazarewicz@samsung.com]]) and the INF files have been
+hacked by Marek Szyprowski ([[mailto:m.szyprowski@samsung.com]])
+basing on the [[file:linux.inf]] file provided for Ethernet gadget
+and description from [[file:gadget_serial.txt]].
