Still not reading my asicminer tubes.
Well now, it could be useful know your settings... For example, you didn't answer me, did you tried with superuser mode?
Sorry must have missed that question, but yes superuser mode is on. Here are my settings right now. Thank You again for the help!


Last try is looking what the miner is doing while tries to start, so get a terminal window in Minera and try launch this command:
/var/www/minera/minera-bin/cgminer -c /var/www/minera/conf/miner_conf.json
(stop any running miners)
If you are still getting "No devices found", try to run:
lsusb
And give us the output
