[xubuntu] Arduino /dev/ttyACM* changes

view story

http://ubuntuforums.org – I apologize in advanced if this is in the wrong section. I have an arduino hooked up to a xubuntu box via a usb/serial connection. A perl script interacts with this arduino and all is well on that front except for the constant renaming of the arduino /dev file. I'm not able to use the arduino with any sort of consistency due to the device changing from ttyACM0 to ttyACM1 or anything higher; I'm forced to open my perl script up and change the device name. My question is, might there be a way to solidify the device name? I never unplug the arduino and don't have any other devices tha (Hardware)
