USB1 and USB3 are routed to two external connectors, while USB2 is used
for the integrated webcam.

Note: connecting a USB mouse to USB3 works properly and lsusb also detects
the integrated webcam, though I haven't tested whether the camera actually
works.
USB1 doesn't seem to work, but I suspect that might just be because it's
used for recovery mode and we can't switch it around at runtime yet.
