The bug was first reported more than one year ago. Additionally, so called "duplicates" max even be different bugs: I've already reported such a similar but possibly different bug #184382 "ehci_hcd: usb disk detection requires un/loading" where also *loading* of ehci_hcd is a workaround.
I would very much prefer a general debugging strategy starting from a design document down to the actual implementation: Could you please give me pointers to relevant documents, e.g. what *should* happen when plugging in a USB device -- beginning from an architectural point of view and ending at the actual implementation / source code level. At a first glance, this approach seems to be annoying. However, even very experienced software experts like me absolutely have no (practical) chance of contributing to this bug (group ?), since most of us have no a priori knowledge of all the gory USB details at hardware and kernel implementation level. Experience, i.e. bugs reports, tell us that USB support is not trivial.
