If I buy a stand alone single unit or two, is there anything else I will be needing?
Does a standard USB port/wall adapter power these?
It can only do SHA-256 with the controller? or is that going to be fixed soon so that units without the controller can do SHA-256 as well?

RIGHT NOW, they will only mine scrypt without the controller but they power up all cores and run at full power (again, without the controller). Std USB port will work but its got to be a single digit port (CPUMiner does not support double digit port numbers). A wall adapter would work but it needs to be 5AMPs or greater PER miner until they figure out how to turn off the BTC cores. You can probably run these things off of solar power with the BTC cores turned off! LOL!
They will however mine scrypt @ ~9w if run them on a linux machine with the gridseed cpuminer -- https://github.com/gridseed/usb-miner/tree/master/software/cpuminer
I had mine sitting on a table next to a GPU rig, got frustrated the setup on controller didnt work right for me, plugged the USB hub into the GPU rig, downloaded/compile cpminer, seems to work fine, stable so far around 300kh/unit.
I had one running off a single PS and put my KillaWatt on it and it showed 9.0 - 9.1w while mining scrypt and finding blocks.
I probably did something stupid/wrong on my the controller setup, will report back when / if I get it working.
With more of these out in the field and the code on github, I'd expect that someone will put together some decent, clean control software. If you read some threads from other people selling, there are various issues with the speed, stability, and even malware with some of what people are getting.
