How to get into OSX when keyboard and mouse don't work?

I was so close to having everything figured out but unfortunately one mis-cue left me unable to login to my main drive, my backup drive, or my usb boot drive for some reason. I posted this thread earlier and got some good suggestions. I followed the advice and added the SSDT from the same board as mine and removed USBMap.kext. Maybe I shouldn't have deleted that kext, but regardless my mouse and keyboard will not work past the bios.

Both backup and main drive load to the login but I can't do anything and then I get the circle with a slash though it for the usb installer. Not sure where to go from here. Seems like I might have to start completely over (at least on the backup drive) given every method I have won't work. Any suggestions would be appreciated.

How do I get into my main drive now to add the kext back in? Is it that I need USBMap + SSDT or do I need USBInjectAll + SSDT for usb's to be recognized?
