Until now I didn't used "git bisect", but I think I need a "good" and 
"bad" commit. Can "git bisect" be used on a rebased tree like linux-next?

I don't know if the USB enumeration on the B+ did work on any 
stable/mainline/next tree. I only know that it works on Piotr's tree 
which contains non upstream patches: 
(But Piotr has only a B rev 2.0 where the USB enumeration worked for him 
with linux-next)

Today evening I will try a vanilla 3.17.1 because it is the base of 
Piotr's tree. If that works I will try to "git bisect" to mainline to 
find the problem commit.
If it does not work on 3.17.1 I try to to find the commit in Piotr's 
tree which makes it working on the B+.

Should I got that way, or do you recommend an another way?

I have only a B+ to test here. I think it affects only the B+.
