This appears to be the latest source for this gadget: https://android.googlesource.com/kernel/goldfish/+/android-goldfish-3 .4/drivers/usb/gadget/android.c We also need some Kconfig/Makefile patch... And configure "CONFIG_USB_G_ANDROID"

Well, this is not sufficient... The android.c file consists of a ladder of #include "f_something.c". This means these files have to be added as well!

According to: http://elinux.org/Android_Mainlining_Project there has been some work, and there was already some code in Linux 3.5 - 3.9 for a ccg (Configurable Composite Gadget - reincarnation of Android Composite Gadget): http://lxr.free-electrons.com/source/drivers/staging/ccg/?v=3.9 It is not immediately clear what happened to it in 3.10/3.11.

The initial Configurable Composite Gadget from Linux 3.5 has been added to the code, but not yet been tested. To configure it, one must unconfigure the other gadgets (mainly the usb-ethernet gadget).

The ccg has now been removed because there appears to be a better patch from Linaro that is compatible to the Android sysfs node names.

I've now integrated the ADB driver from the official AOSP 3.10 kernel tree: https://android.googlesource.com/kernel/common/+log/experimental/andr oid-3.10/drivers/usb/gadget/android.c Our 3.12-wip-replicant4 kernel now boots to the Android UI and it is possible to connect with "adb shell" from the host.
Status:
Fixed

Here is a VERY interesting comment by John Stultz, that it is possible to use adb via the FunctionFS driver, which is already part of the mainline Linux. It is not as flexible as the original adb driver, though. https://plus.google.com/111524780435806926688/posts/AaEccFjKNHE Progress is tracked here: https://blueprints.launchpad.net/linux-linaro/+spec/android-adb-upstr eaming
