I don't think the parallel port is meant to be hot-swappable - you'd
need to reboot if you wanted to change between one and the other.
If either of them has a 'through' adaptor (probably labelled `to
printer'), then you should be able to daisy-chain them, so it's even
easier than hotplugging.
Both my SyQuest SparQ and my FreeCom CDRW have a through port. I plug
one in after the other, and load the modules for each, and both wll
mount as normal. I can even burn from the SparQ to CD (though never at
greater than 1x). I need to have the module dependencies and modprobe
arguments set up carefully though, because they use different adaptor
protocols (pcd and pg for friq, and pd for epat) and if I don't specify
the arguments right, the kernel may hang for a few seconds while it
looks for one type of drive under the other adaptor.
Of course, this probably isn't a problem if there's no overlap between
the adaptor protocols, and with a scanner and a HD you're probably OK.
Going to Oxford is only `going up' if you start off south of it.
