I've been struggling with this for two days now (over 27h of working on it). For the life of me I can't get Chameleon to detect other USB devices on the system. I cheated and put Snow Leopard on the same USB as Chameleon (Apparently I didn't copy it all as I got a big fat X at the boot screen after 4~ minutes), showed up no problem.
Is anyone else having this issue? I think it's a bug (hardware?) so that's why this is here.
