Here's the big USB merge for the 3.4-rc1 merge window. Lots of gadget driver reworks here, driver updates, xhci changes, some new drivers added, usb-serial core reworking to fix some bugs, and other various minor things. There are some patches touching arch code, but they have all been acked by the various arch maintainers.
