This is what I collect from a ssh, running multiple lsusb commands.

At first only the two external devices are listed, apart from the hubs:

solitone@alan:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 04b3:3025 IBM Corp. NetVista Full Width Keyboard
Bus 001 Device 002: ID 046d:c05a Logitech, Inc. M90/M100 Optical Mouse
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Then one of the two integrated usb devices (maybe the keyboard, I haven't 
checked, so I don't know for sure) is detected:

solitone@alan:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 05ac:8290 Apple, Inc.
Bus 001 Device 003: ID 04b3:3025 IBM Corp. NetVista Full Width Keyboard
Bus 001 Device 002: ID 046d:c05a Logitech, Inc. M90/M100 Optical Mouse
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

After some further time, also the second integrated usb device (perhaps the 
trackpad) is detected:

solitone@alan:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 05ac:0273 Apple, Inc.
Bus 001 Device 004: ID 05ac:8290 Apple, Inc.
Bus 001 Device 003: ID 04b3:3025 IBM Corp. NetVista Full Width Keyboard
Bus 001 Device 002: ID 046d:c05a Logitech, Inc. M90/M100 Optical Mouse
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

devices and the integrated keyboard and trackpad continue to work.
