I'm familiar with it - as I said, it's not being seen as a USB device at
all.  Hence one can't get to the stage of accessing /dev/ttyUSB1 because
the kernel hasn't noticed that something has been plugged in.  There are
no log messages on the parent computer when the Sheevaplug is connected
to it.

Presumably something within the Sheevaplug is trying to signify
something by flashing the 3 LEDs twice a second, but so far I've been
unable to find out what.

The odd thing is that if you disconnect all leads from the Sheevaplug -
power, ethernet and USB, the flashing carries on for quite a long time
afterwards.
