These are all the logs I get booting a 10.0 install iso with

It's probably OK until it restarts but the seems to be stopped. Anybody
wants to have a look? Maybe start with finding what the states mean.
I get the same with two usb-ohci controllers (so 6 ports) running Mac OS
9.0.4:
usb_ohci_set_ctl pci-ohci: new state 0x80

So both usb mouse and kbd do not work.
the pcap file for the mouse stalls here:
12 0.007048 0.1.0 host USB 64 SET CONFIGURATION Response
Maybe the driver gets something from the emulated HID device that it
cannot
handle and stops during init? Can you reproduce the same with OS X 10.0
and
try to correlate the events you see in pcap and trace with the driver
source
or find out how to enable and read the messages in the driver (unless
these
are stripped from the binary in Mac OS X but maybe there's something in
the
guest logs; ave you checked those?) In QEMU the usb-kbd and mouse are
implemented in hw/usb/dev-hid.c but this file does not have any debuging
or
traces. You might try to add some printfs for testing.
However, when I use the usb probe tool from the USB DDK, to probe the
buses
I see the host emit a get descriptor
13 115.761725 host 0.0.0 USB 64 GET DESCRIPTOR Request DEVICE
14 115.761803 0.0.0 host USB 72 GET DESCRIPTOR Response DEVICE
15 115.773719 host 0.0.0 USB 64 SET ADDRESS Request
etc. and this time the mouse is recognised as HID device, the host
starts
polling it and mouse and kbd start to work.
It could be possible that the driver did not get to this point but once
something else get's past that it recognises the device but I have no
idea
how this works and not even sure which OS you had this result with. Is
this
still 9.0.4? That's hard to debug because we don't know what its driver
is
doing.
Is there a Darwin, OpenDarwin or whatever was that called during the
years
iso that boots on this machine (also on the real one)? That should be
fully
open source and probably have the same drivers as Mac OS X so
reproducing
with that could give some more info or maybe its driver is more verbose
about
errors and has debugging. So you could try to find an early Darwin
version
that's about the same time as early OS X versions or look at the
IOHIDFamily
and try to find what part of it is running when you see the logs (as
this
driver is quite complex it may not be easy).
The oldest Darwin CD I could find is 6.2 which boots and works so it's not
old enough for us.
The simplest driver is in the oldest 10.0 version so maybe we should try
to look at that:
https://github.com/apple-oss-distributions/IOHIDFamily/tree/IOHIDFamily-6
and the low level part is in the xnu kernel:
https://github.com/apple-oss-distributions/xnu/tree/xnu-123.5/iokit/Families/IOHIDSystem
I don't quite know how it works and where it starts running but a large
part of it looks like it handles key mapping. While booting I see an error
from OpenBIOS saying:
call-method slw_update_keymap failed with error ffffffdf
Could this be related to the problem? What is this error about? This
PearPC bug has some info on where it may come from:
