In the meantime I have been able to capture more verbose debug traces
(with CONFIG_USB_DEBUG=y on Kernel 3.2.9 x86_64). The photograph I am
copying this from is a little blurry (I had to hurry exiting a train),
so some numbers may be wrong...

I hope this makes more sense... The original photograph is available

Please let me know if you prefer a Bugzilla report instead of this mail.
