Hi again.
I made a new full git bisect from the linux root directory this time.
And now I have a different place for the first "bad" commit:
5c80cc78de46aef6cd5e714208da05c3f7f548f8 is the first bad commit
commit 5c80cc78de46aef6cd5e714208da05c3f7f548f8
Author: Andreas Herrmann <andreas.herrmann3@xxxxxxx>
Date: Thu Sep 30 14:43:16 2010 +0200
x86, amd_nb: Enable GART support for AMD family 0x15 CPUs
AMD CPU family 0x15 still supports GART for compatibility reasons.

From what I could undertand with my very little knowledge, the bug
could be caused by the addition of new id.
Below is the full bisect log:

Probably you found the wrong commit. A merge should not cause any
bugs.
I bisected directly from drivers/usb. Could it be the reason ?
Yes, it could.
