Help running cgminer on Ubuntu 14.04 - waiting for USB hotplug devices, and other errors I'm a total noob regarding bitcoin mining, I've installed cgminer using apt-get install but I can't get it to work.

I start it with this command:

./cgminer  -o stratum+tcp://www.albamine.net:3333 -u Weblogin.WorkerName -p WorkerPassword


I followed these instructions:  (I'm mining for scotcoin.)


  
  Install Ubuntu
  Install updates
  sudo apt-get update
  Install updates for your graphics card
  Install misc packages
  sudo apt-get install gedit git libcurl4-openssl-dev libncurses5-dev pkg-config automake yasm
  Edit grub configuration
  sudo gedit /etc/default/grub
  Edit GRUB_TIMEOUT=10 to GRUB_TIMEOUT="10"
  sudo update-grub
  Download ATI OpenCL drivers. Untar it and run the script inside.
  Reboot.
  git clone git://github.com/ckolivas/cgminer
  Download the ADL SDK. Unzip it. Copy the include directory into cgminer, and name it ADL_SDK
  Check dependencies for cgminer.
  cd ~/cgminer
  ./autogen.sh
  Create the build script:
  CFLAGS="-O2 -Wall -march=native -I /opt/AMDAPP/include/" LDFLAGS="-L/opt/AMDAPP/lib/x86_64" ./configure
  make
  Run using
  export DISPLAY=:0; export GPU_USE_SYNC_OBJECTS=1; ./cgminer -n
  


The first few times I tried I got an error that repeatedly said:

KnC spiL Can not open SPI device /dev/spidev1.0: No such file or directory.


NowI'm getting a terminal that looks like this, and I have no idea. I've googled select sections of the code but can't figure out what it's all about. Any suggestions would be gratefully received. Thanks.



Info. Running Ubuntu 14:04 on a System 76 Galago Ultra pro.
Your system reports: Intel's new Iris Pro graphics.

As far as ubuntu 13.10 was concerned the package cgminer was compiled for nvidia graphics cards and installed the module for ubuntu.

Consider running a system with dedicated GPU w/ PCIe: e. g. nvidia and ATI and possibly compile cgminer by yourself.

I tried bfgminer for ubuntu now, see here: http://jarco.be/install-bfgminer-ubuntu-mint/

...but cannot get it to work for litecoin scrypt right now...

NOW up and running bfgminer compiled for ubuntu 14.04 with howto from here:
https://debianhelp.wordpress.com/2012/01/02/bitcoin-mining-in-ubuntu-with-bfgminer/

with some minor changes:


installed "bitcoin-qt" instead of "bitcoin"
sudo apt-get install uthash-dev
./autogen.sh &amp;&amp; ./configure --enable-scrypt --enable-opencl &amp;&amp; make
modified ".bfgminer/bfgminer.conf" can be pasted here, if you want
