Makes Chrome hang when using USB devices.
Original issue's description:
> Parse USB interface association descriptors.
>
> USB interface association descriptors are used to combine multiple
> interfaces into a single functional group. This patch adds support for
> parsing them out of the |extra_data| field left by libusb's parsing of
> configuration, interface and endpoint descriptors. The resulting
> association is then represented by setting the |first_interface| field
> of each interface in a function to the |interface_number| of the first
> interface in the function.
>
> WebUSB will use these associations to set permissions for an entire
> function with a single descriptor.
