Hi Sebastian,

what I meant was that you start all steps that you previously described
with one initial mrproper, i.e.:

1) make mrproper
2) make menuconfig and select the gadgets with 'm', then save and exit
3) make menuconfig and select 'y' for "USB Gadget Drivers", then save
   and exit.
4) Check for problems either with menuconfig or directly in .config

With that initial mrproper I was not able to reproduce the problem
and therefore I suspect some content of an existing .config causing
the problems.

Dirk

PS: Probably `make mrproper' can be replaced by `rm .config' but I tested
    it only once and cannot say for sure.)
