You mean that you unplug the device without unmounting it? This is
somewhat dangerous, but it should still work.

Is that really everything? It does not tell about the sda device and
the first partition the second time? Then there is really something
wrong with your kernel.

If you just forgot to paste these lines, can you please look in the
Device Manager wheter the device properly shows up the second time and
has a child node called 'Volume'?

Thanks,

Martin
