There was a misinterpretation of how the v2 header works. The flags
in the header indicate what is in the rest of the structure.

The patch "[RFC] usb: gadget: f_fs: Add flags
to descriptors block" marks the current
usb_functionfs_descs_head format deprecated
and introduces support for sending SuperSpeed
descriptors.
This CL makes adbd to send Descriptors in the
new format. Adbd would fall back to the old
format, if kernel is not able to recognize
the new format. This is done to prevent
adbd from breaking in the older versions
of the kernel.

In kernel(3.10) USB ADB gadget driver is removed.
Using Functionfs for USB adb gadget.
Android recovery uses a stripped down version
of adb command for sideload only. It's missing
the ffs function support, so add the ffs
support to allow sideload command to work

Rather than depending on the existence of some place to store a file
that is accessible to users on an an unbootable device (eg, a physical
sdcard, external USB drive, etc.), add support for sideloading
packages sent to the device with adb.
This change adds a "minimal adbd" which supports nothing but receiving
a package over adb (with the "adb sideload" command) and storing it to
a fixed filename in the /tmp ramdisk, from where it can be verified
and sideloaded in the usual way. This should be leave available even
on locked user-build devices.
The user can select "apply package from ADB" from the recovery menu,
which starts minimal-adb mode (shutting down any real adbd that may be
running). Once minimal-adb has received a package it exits
(restarting real adbd if appropriate) and then verification and
installation of the received package proceeds.
always initialize usb product, vendor, etc. for adb in recovery
Set these values even on non-debuggable builds, so that the mini-adb
now in recovery can work.
