I found the problem. When the ZIF adapter came in, I re-flashed all the PICs on the Zeus and then ran the Zeus utility, and everything worked just fine. Going back to the Hub and SSC, I re-flashed them, and... nada. I had understood from reading and the comments here the Zeus SSC utility is different from the regular SSC utility. What I hadn't realized is the SSC utility for the modded V1/2 SSCs is also different from the V1 utility. I copied the SSC V3 file ove the SSC V1 file, and all is well. Honestly, the Wiki could be a bit clearer, and better yet, the version numbers on the software should be different. It would be great if the software also listed right up-front which modules it supports. Better still would be a single, unified SSC / Zeus utility.
