I'd like to mine with my Intel HD Graphics 4000 (128SP 16C 350 MHz/1 GHz, 1.8 GB DDR3 1.6 GHz 64-bit, Integrated Graphics). I think it has support for OpenCL, as I ran benchmark software, and it said it has.
So I tried to use CGMiner on Windows in the single pool mode:
cgminer -o http://pool:port -u username -p password
But it said it could not find any devices:
