Oh, one more thing, you can check what Tellico is doing with strace. For 
example, here's the output for me:

robby:>strace -e trace=open src/tellico 2>&1 | grep dev
open("/usr/lib64/libudev.so.1", O_RDONLY|O_CLOEXEC) = 3
open("/dev/urandom", O_RDONLY)          = 11
open("/dev/urandom", O_RDONLY|O_CLOEXEC) = 12
open("/sys/class/video4linux/video0/dev", O_RDONLY) = 15
open("/sys/class/video4linux/video0/device/modalias", O_RDONLY) = 15
open("/sys/class/video4linux/video0/device/../speed", O_RDONLY) = 15
open("/sys/class/video4linux/video0/dev", O_RDONLY) = 15
open("/sys/class/video4linux/video0/device/modalias", O_RDONLY) = 15
open("/sys/class/video4linux/video0/device/../speed", O_RDONLY) = 15
open("/sys/devices/system/cpu/online", O_RDONLY|O_CLOEXEC) = 6
