Heh, you just did bisect it down to the range of changes, which is what I asked for, thanks :) Alan, this points to your 2d93148ab6988cad872e65d694c95e8944e1b626 commit that was added to the 2.6.27.23 kernel. Hm, maybe that means we need to also add your f9c99bb8b3a1ec81af68d484a551307326c2e933 commit, what do you think? thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
