Flight 5 problems with USB mouse hotplugging

[Paul]

As I understand it, hotplug has been replaced by udev.
But now hotplugging the USB mouse into my laptop no longer works.

What am I doing wrong?  Do I need to manually to add the
USB mouse as an input device in xorg.conf?  Didn't have to
do that in Hoary/Breezy/etc.

$ cat /etc/issue
Ubuntu 6.04 "Dapper Drake" Development Branch \n \l

Hotplugging the USB mouse is detected by the kernel and udevmonitor,
but the mouse has no effect on the X11 pointer.
