STM32F429 Discovery Kit - Plug it in

After sitting in a box for 5 years, here we go. I dig a mini-USB cable out of my box, connect it to the ST-Link port, and plug it into a USB port on my linux desktop.

Several LED's light up:

And the display has stuff displayed! I have 6 options. And the display is a touch screen! I press "system information" and it tells me: 

Core Cortex M4F
CPU speed 168 Mhz
Firmware 1.0.3
Copyright 2013 STMicro
This is all very cute, but lets me know that my board is healthy.

My linux logfile shows:

Note that this says USB full-speed, not high-speed.

I connect picocomm to ttyACM1 and get no response.

Linux mounts the mass storage device and shows me 2 files:
