A device answers only the kinds of questions it lists here, so check this before you ask it anything. These values are flags, so a device can list more than one.
Protocol negotiation is on the list even though MIDI-CI version 1.2 dropped it, because UMP stream messages now do that job. Devices made before then still list it, so you may see it.
| Value | Number | Description |
