I'm not using udev yet, but I do have hotplug/usb-mount working. For that, I
use a /etc/hotplug/usb/usb-module a bit different from the one provided by
usb-mount. Here it is:

[root@idolize root]# cat /etc/hotplug/usb/usb-storage
#!/bin/bash

/usr/bin/logger -t usb-storage -p user.notice "$ACTION DEVICE=$DEVICE DEVPATH=$DEVPATH"

if [ "$ACTION" = "add" ]
then
    # Sleep a while, until $DEVICE exist
    tries=5
    [ -n "$DEVICE" ] && file="$DEVICE" || file="$DEVPATH"
    while [ ! -e "$file" -a "$tries" -ne 0 ]; do
        sleep 1
        tries=$(($tries-1))
    done

    /usr/bin/logger -t usb-storage -p user.notice "Adding $file"
    /usr/sbin/usb-mount < /dev/null 1> /dev/null 2>&1
fi


Note that it waits the DEVICE/DEVPATH be created before calling usb-monut,
and timeout after 5 tries (1 try per second).

hope it helps.
