iirc, interrupts are disabled while you're at the mountroot prompt,
which freezes usb enumeration.  It should do a sleep/pause every time
you enter '.', which should allow the interrupt-driven enumeration to
finish.  It's been a long time since I've done it, but it seems to
still work... I just plugged in a usb drive while I was at the prompt
and it didn't show up until the second time I entered a '.'.
