Does the mini pac have the same programming capabilities as the i-pac? I have the Ipac and found that the software it comes with was really complicated and didn't work well for me, but the Ipac has a built in config menu system that you can open in any text program (like notepad). You need a pass-through keyboard attached and you just press crtl+shift+p (or ctrl+alt+p, sorry can't remember, one of them is print though, so it's not that one) and a menu pops up. It's really easy to assign keys this way, you just press the button on your control panel, then press the key on the keyboard you want to assign to it.
Hope this helps
