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).
