That's your problem...  you should be seeing something more like

Sep  6 09:13:02 snowball kernel: [1030652.496395] usb 5-2.1.4: new high-speed USB device number 13 using xhci_hcd

Of course, the strings I'm showing are for a different phone!   Most
commonly when I've seen a device fail to enumerate, the problem has been
the cable (I know, you've already said you've tried multiple cables).
But you need to be enumerating before absolutely anything else will
happen and before anything else is relevant...  you aren't having
trouble with other USB devices?  No chance there's a USB enable/disable
on the phone?  (on mine, things enumerate properly like I showed, but
nothing else happens until I select "USB for file transfers" in a
dropdown on the phone).
