Replying to my own posts (and top-posting as well!) might be a bit off-form,
but I've found the problem (to save anyone wasting time thinking about it).
I read on Google that some CD writing software was causing some people USB
problems, as it had a tendency to alter things, so I uninstalled mine, which
came free with my DVD-R drive, deleted shared .dll files when the
uninstaller offered to, and whaddya know, I got the card reader back!
Regards,
Stuart.
