urg_node vs hokuyo_node

I am new to ROS and what I want to do is create maps for my robot with hokuyo lidar range sensors. I installed urg_node and hokuyo_node on my precise Hydro distribution of ROS. I dont understand what the difference between these 2 nodes is and which one should I use. Is it true that urg_node is simply a new version of hokuyo_node and I shouldn't have installed hokuyo_node? Also, some of the tutorials that explain how to use hokuyos only use hokuyo_node, so I'm a bit lost. My hokuyo device keeps being assigned a device name /ttyACM1 instead of /ttyACM0 which is why urg_node no longer works and I can't get laser data in rviz.

Can anyone please HELP!!??
