I just got mine! However, there was a bad wire (looks like it broke off the connector).
take the cable and go to your local radioshack, its just a normal flat with 4pin connector
then after you got the replacement one from sushi you can try return it to them

Hmm... not a bad idea. Right now I stripped the wire a bit and stuck it in there. It's making contact but you can pull it out easy (so I put it in a place where no one touches it!). It looks like I'm up and running at 180 GH/s! Lovely - first try to, and other than the broken wire, it's working as advertised!
PS: Found the IP address label on the controller board. Before I found it, I found the IP address by doing a scan on the 192.168.2.x subnet.
