journalctl: what does “New USB device found” mean?

Aug 17 02:16:44 <hostname> kernel: usb 1-2: new high-speed USB device number 13 using xhci_hcd
Aug 17 02:16:45 <hostname> kernel: usb 1-2: New USB device found, idVendor=05c6, idProduct=aaff, bcdDevice= 3.18
Aug 17 02:16:45 <hostname> kernel: usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Aug 17 02:16:45 <hostname> kernel: usb 1-2: Product: Android
Aug 17 02:16:45 <hostname> kernel: usb 1-2: Manufacturer: Android
Aug 17 02:16:45 <hostname> kernel: usb 1-2: SerialNumber: 0123456789ABCDEF

Above is a snippet from my journalctl output. Are entries stating new USB device found... a log entry of a USB device being plugged in to my system? I didn’t plug any USBs today. So was wondering if this could be something worrying as someone else trying to access my computer when I am away?

TIA!
