This message is result of usbmuxd -f command.

-f means:

Do not daemonize (implies one -v).

-v means:

be verbose (use twice or more to increase verbose level).

Since usbmuxd operates in hot-plug mode, it attempts to monitor all connected devices. The -f flag causes the -v flag to produce expanded output, and we see output messages like these. This message does not affect startup.
