-The cable is named `Command8 MCU` on Linux and macOS. On Windows, WinMM names
-cables positionally and ignores the jack strings, so it appears as
-`MIDIIN4 (Command|8 Bridge)` / `MIDIOUT4 (Command|8 Bridge)` — the fourth port.

-Verified on hardware 2026-08-11: Reaper driving a Command|8 through the dongle

+| OS | Port name |
+|----|-----------|
+| Linux (ALSA) | `Command\|8 Bridge Command8 MCU` |
+| macOS (CoreMIDI) | `command8-cpp - Command\|8 Bridge - Command8 MCU` |
+| Windows (WinMM) | `MIDIIN4 (Command\|8 Bridge)` / `MIDIOUT4 (…)` |

+ALSA and CoreMIDI read the per-cable jack strings; WinMM ignores them and names
+cables positionally, so on Windows it is simply **the fourth port**.

 The translation is the same `src/mcu/c8_mcu.c` this repo unit-tests on the
 desktop; the firmware compiles that file directly rather than a copy.
