Very cool, I use CrazyGuy's R1 for my U3, too. I noticed that it's missing frequency 250, did you do a write up how to add missing frequencies? I'd like to add that one back in, even though I run my U3 at 237.5 freq normally.
I will document what I have done over in the R1 thread when I get a chance to consolidate the work, also ideally want to get aaron6 cgminer-gekko running as he reports it as handling the Compac better. I sometimes have to replug after switch on to get it hashing.

if you want to send me CG's backup file i can see what he changed and put the cgminer in there for the compacs.
