No, I'm not a (re)seller. The only reason I even have one myself is because it's a StickMiner (albeit for Scrypt, but it was unique enough to warrant getting one when I saw it up for sale for cheap).
If you got the screen where it's showing a hash rate (which looked okay for 3 devices plugged in - presuming you did have 3 of them plugged in) - it should already be working as that's a number cgminer calculates automatically from work returned by the hardware; just give it time to show shares accepted/rejected for the pool.
Again, though, mine worked pretty much out of the box ( config is in post somewhere above, but tl;dr: plug in, wait for driver install, run GUI, adjust pool, off it goes. Maybe one detail, that's also in cybtc's guide, is that I probably changed the switch position to the corner when I first messed with it. Don't ask me what that switch does, I never checked

) - if you just cannot get it working on your machine for whatever reason, see if you can return them, or put them up for sale.. see if somebody else has better luck with their machine.. the hardware itself - barring any actual defects - should be fine.
