I've just discovered that automounting of USB drives isn't working on my xubuntu 11.10 system.

I can see the device with lsusb:-

Bus 002 Device 005: ID 0951:1607 Kingston Technology DataTraveler 100

but no sign of it automounting.

The "Mount removable drives when hot-plugged" setting is ticked and it always used to work (though I'm not absolutely sure it has worked since I upgraded to 11.10).

Any ideas?
