That line of disconect usb device is normal. I am more concrenred about pic update fail, i do not have it on my miner.
Also, no forwading state in kernal. Check network, and provide more data, what kind of connection you using ( wireless etc)
Also see firewall notice. Try with only one pool, use btcguild if you are in eu. We need more info to help you, syslog are not enough.
Do not wotty about bitmain device is now disconnected - its normal. Bitmain asic is registered, you can not detect device using cigminer comline. Cigminer hang out because there is network problems, or pool setings you use. Hashtest are fine. Imo you have network problems. Make hard restart on rooter as well miner, that often help.
Some member with teamviewer can help you.
