Just debugged the following:
ehci_setup() happens. Starts a thread to probe its ports...
ohci_setup() happens. Starts a thread to probe its ports...
OHCI probes port zero, decides there's nothing there.
EHCI probes port zero, decides there's a USB1 device there and gives it
away to OHCI... which is never going to see it.What's wrong here? I've "fixed" it with a wait_threads() right before the ohci_setup() in usb.c and now I can see my keyboard, but that's definitely not the right answer. Do we have any kind of hotplug support for USB devices? If not, should we at least have a kind of "manual" hotplug notification for when EHCI actively gives a port away to the USB1 controller? (How) is this supposed to work? -- dwmw2
