This patch series is intended to demonstrate the possibility of using adbd (Android Debug Bridge daemon) with a generic FunctionFS gadget instead of a custom adb gadget from Google. In order for this to work, the patch number 1 from this series introduces iSerialNumber which is set from a kernel module parameter named usb_serial. Patches 2 and 3 are used to add a replacement usb access layer to adbd: patch number 2 adds a new layer as a copy of an existing usb_linux_client.c while patch number 3 introduces FunctionFS support proper on top of patch number 2. The former usb access method is still available, the method is chosen at compilation time by setting USE_USB_FUNCFS variable to false in adb's Android.mk in the section dedicated to adbd. For information on the background please refer to this post: http://thread.gmane.org/gmane.linux.usb.general/56244 http://thread.gmane.org/gmane.linux.usb.general/56245 How to use on the target device: $ insmod g_ffs.ko usb_vendor=<vendor ID> usb_serial=<some string> $ mount -t functionfs adb /dev/usbgadget/adb -o uid=2000,gid=2000 $ ./adbd In case adbd does not switch its identity to uid=2000,gid=2000, respective options are not required in the mount command above. It depends on adb properties. If adbd is run standalone, then the properties are set to their defaults which imply switching uid,gid to 2000,2000. [PATCH 1/3] usb: gadget: iSerialNumber for FunctionFS - iSerialNumber as a module parameter, FOR KERNEL [PATCH 2/3] adbd: add a new usb access layer - Copy an existing usb access layer to form a new usb access layer, FOR ADBD [PATCH 3/3] adbd: introduce FunctionFS support - Modify the newly created usb access layer to support FunctionFS, FOR ADBD I also have a kind request to forward this post to Android people (or should I say "people from Android" instead? ;) ) who might be interested.
