Mac Mini and a new Digi 002 Still not recognizing pleasehelp

[noisebrigade]

I bought a used Digi002R on ebay. When I plug in the Digi002R into my Mac mini, the 002R is not recognized when starting the Protools LE 6.9.3 application. The hard dive that is plugged into the back of the 002R is also not being recognized on the Mac Mini, not even in Disk Utility. I proceeded to check the hard drive by plugging it directly into the mac mini and it mounted without any issues. I tried starting up the Protools 6.9.3 application with an Mbox and Protools LE 6.9.3 worked flawlessly.
I thought it could not be loading due to a compatibility issue with Protools 6.9.3, so I uninstalled Protools 6.9.3 and installed Protools LE 7.1. Again, the harddrive mounted without issue when plugged directly into the Mac mini. So, I unplugged the harddrive, plugged in the 002R, and again, Protools did not recognize the hardware. The harddrive, when plugged into the back of the 002R, also did not mount on the Mac mini and was not recognized in Disk Utility. When I tried starting Protools LE 7.1 with the Mbox it started flawlessly.
I returned the used unit and bought a brand new Digi 002 and I still have the same problem. Could it be a setting problem on my Mac Mini? What am I doing wrong? Am I facing the wrong way when praying to the Digi Gods? Please help.So, at this point I am at a loss. Any ideas? Please? Email me at [email protected] thanks so much.
