This patch fails to merge because of the recent usb changes in omap. Please rebase this patchset and resubmit.

Most (All ?) of the configs I reviewed set the addr element to a valid address. I do not believe 0 is a valid address on omap. If the intent is a double negative {0, 0} == probe all then add a comment.
