Is there a version of cgminer, bfgminer or sgminer to drive these if I wanted to run them without the controller card?
i think we simply need one of these software..
https://github.com/gridseedit's a modification of either cgminer or cpuminer..
both can be compiled under linux or under windows ( windows might be a little bit complicated: using MinGW )
we have to choose.. either cheap & fast product OR good documentation ^^
