0x0007 deviceFriendlyName

The user-assigned name for a device — the custom label you can give a mouse or keyboard, distinct from the fixed marketing name in 0x0005 deviceTypeAndName. getFriendlyNameLength reports the current, maximum, and default name lengths; getFriendlyName / getDefaultFriendlyName read the name in 15-byte chunks (or the whole-name convenience wrappers); setFriendlyName writes it and resetFriendlyName restores the factory default.

OpenLogi reads the friendly name during device discovery and surfaces it when it differs from the default.

Spec: Logitech HID++ 2.0 — x0007 deviceFriendlyName. Used by: device identification.

Full function reference coming soon.
