The replacement unit was because my old one died.  Probably due to 
southbridge meltdown.  I will be looking for a better cooler for that 
thing, it'll give you a blister if you leave your finger on it.

I believe the kernel usb bus log message spamming was fixed between 
2.6.22 and 2.6.22-git16.  I haven't installed any other kernels or 
finished looking at the kernel commit logs yet to see which one fixed 
it.  I just went straight to the latest kernel that was available today 
and was going to start troubleshooting from there.  I enabled 
CONFIG_USB_DEBUG and went to start testing and the problem wasn't 
there.  I am happy I can use my console again.
