I have a new memory card reader which 'does all the right things' when you plug it in but nothing appears on my desktop. An older, very similar, device works OK and the memory card appears as a drive on my desktop.
How does one diagnose this sort of problem? When I plug in the reader (and card) that doesn't work I see the following in syslog:-

So what's wrong?
