Have you been able to successfully connect a USB 2 device to this controller?  
The behavior I've seen on a couple ICH4 boards is that the controller gets 
recognized fine and USB 1 devices work (through UHCI).   However, as soon as 
I connect a USB 2 device, I get the "controller halted" and "disabling port" 
messages.

Tried to debug it but didn't have much luck.  I suspect it's some subtle 
timing bug or other weirdness with Intel's implementation. . .

My two NEC-based ones work ok -- one PCI and one CardBus.  I do sometimes have 
panics with umass, and occassionally the laptop somehow loses all ability to 
deliver interrupts, to anything (almost always when accessing the USB hard 
drive for the first time after a reboot).
