Here are 2 screenshots showing the USB setup on my PC. I'm not sure how to read this but I think its showing that both SBIG cameras are on the same root hub? If this is the case how do I get it to a different one? I'm working on doing testing with the cameras now, I can tell you the problem is still there if the ST-8300M camera is powered off but still physically connected to the PC. I'm checking to see if my friend who lives onsite can unplug everything but the STi from the PC, if not I'll have to test it next time I'm at the observatory. I've also attached a series of guide images during each test.
