Sorry, I pasted this from my own terminal. Of course, it needs to be:

  echo 0 > /sys/bus/usb/devices/2-1.3/bConfigurationValue

This assumes that device names stay the same. They will stay the same
if you connect the same devices to the same ports as before. If unsure,
see 'dmesg' and 'lsusb -t'.
