Hi,
I meant that instead of falling back to "combined-interface" probing we could assume that all interfaces with three endpoints are "combined" and simply ignore the union and call managementy. descriptors and all the ways that devices may have gotten those wrong.
I am afraid we would break the spec. I cannot recall a prohibition on having more endpoints than necessary. Heuristics and ignoring invalid descriptors is one things. Ignoring valid descriptors is something else.
I was thinking more of the individual entries in the device-id table whose control interfaces may not even be of the Communication class. But hopefully that was verified when adding them.
Now you are confusing me. In case of a quirky device, why change the current logic?
