com.apple.MobileAsset.MobileAccessoryUpdate.A2119-22G

From The Apple Wiki

The com.apple.MobileAsset.MobileAccessoryUpdate.A2119-22G MobileAsset type contains firmware updates for the Apple USB-C Digital AV Multiport Adapter. It's published in mesu for iOS (manifest) and macOS (manifest).

It was first discovered on 19 May 2024 (2024-05-19) but almost certainly existed earlier.

This seems to be a newer version of com.apple.MobileAsset.MobileAccessoryUpdate.A2119. Based on the name, it might be that this asset is used since macOS 13.5 (22G74).

Software

On macOS, this asset is downloaded by /System/Library/PrivateFrameworks/MobileAccessoryUpdater.framework/XPCServices/USBCAccessoryUpdaterService.xpc/Contents/MacOS/USBCAccessoryUpdaterService, which also handles installing the firmware update into the accessory. On macOS 13, it has "A2119-22G" hardcoded; there isn't any check for "if foo then get A2119 instead".
