Hm, I thought someone tested this previously. Do you have a test case for this that I can try to duplicate the problem for?

p.s. I'd recommend sending these kinds of patches to the linux-usb-devel mailing list too. That's where most of the Linux USB developers are. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
