Note that, only two days after this article was published, Greg Kroah-Hartman removed CCG from the staging-next tree. See, for the first of two patches involved:
This is not in mainline yet, but it looks like CCG is on its way out.

CCG on its way out? Posted Mar 29, 2013 0:04 UTC (Fri) by jstultz (subscriber, #212) [Link]
Yea, so this was maybe not as clear/precise in the summary. But CCG being removed is in part due to some of the discussions at Linaro Connect.
CCG, basically a modified version of the android gadget driver, was merged into staging, but the Android developers decided against moving to use it, and the upstream maintainers want to see a configfs based gadget instead. Thus the CCG driver had been effectively abandoned and developer efforts have been focused on the configfs gadget.
Mix in the fact that the functionfs gadget driver already can also be used for adb, and you get a bit of a mess as to what the right approach is going forward. (How many configurable composite gadgets do we need?)
That said, the configfs gadget driver has been slow-going in development, so if necessary it may be something Linaro would try to help along (rather then "taking over development").
