So set no_dynamic_id in the usb_driver structures.
(But I wonder why USB behaves differently from PCI, which requires that
the dynamic ID's driver_data value (defaulting to 0) matches a value
used in a static ID entry.)
I don't know why USB differs from PCI, but we do need the dynamic ID here as
there are always new IDs being issued. One of the criteria for adding the ID to
the table is that it works OK with dynamic addition. These devices are
frequently reported by users that do not have the skills to build their own kernel.
