[Qemu-devel] qemu 1.4 : ubuntu 12.10 : ehci + companion + usb-tablet -> vmmouse not loaded + usb-tablet not working

[Alexandre DERUMIER]

Hi List,

I'm testing qemu 1.4, without ubuntu desktop 12.10 with graphical installer

I found 2 bugs:

1) vmmouse is not loaded  if an usb-tablet is plugged on an ehci controller 
with companion
---------------------------------------------------------------------------------

4 cases with mixed options:


a)ehci +companion +tablet:  vmmouse is not loaded

qemu command line : -readconfig /usr/share/qemu-server/pve-usb-companion.cfg 
-device usb-tablet,id=tablet,bus=ehci.0,port=6

# info mice
  Mouse #0: QEMU PS/2 Mouse
* Mouse #1: QEMU HID Tablet (absolute)


b)ehci +companion -tablet: vmmouse is loaded

qemu command line :  -readconfig /usr/share/qemu-server/pve-usb-companion.cfg

# info mice
  Mouse #0: QEMU PS/2 Mouse
* Mouse #1: vmmouse (absolute)


c)ehci -companion + tablet : vmmouse is loaded

qemu command line :  -readconfig /usr/share/qemu-server/pve-usb-nocompanion.cfg 
-device usb-tablet,id=tablet,bus=ehci.0,port=6

# info mice
  Mouse #1: QEMU HID Tablet (absolute)
  Mouse #0: QEMU PS/2 Mouse
* Mouse #2: vmmouse (absolute)



d)ehci -companion -tablet : vmmouse is loaded

qemu command line :  -readconfig /usr/share/qemu-server/pve-usb-nocompanion.cfg

# info mice
  Mouse #0: QEMU PS/2 Mouse
* Mouse #1: vmmouse (absolute)


pve-usb-companion.cfg:

[device "ehci"]
  driver = "ich9-usb-ehci1"
  addr = "1d.7"
  multifunction = "on"

[device "uhci-1"]
  driver = "ich9-usb-uhci1"
  addr = "1d.0"
  multifunction = "on"
  masterbus = "ehci.0"
  firstport = "0"

[device "uhci-2"]
  driver = "ich9-usb-uhci2"
  addr = "1d.1"
  multifunction = "on"
  masterbus = "ehci.0"
  firstport = "2"

[device "uhci-3"]
  driver = "ich9-usb-uhci3"
  addr = "1d.2"
  multifunction = "on"
  masterbus = "ehci.0"
  firstport = "4"



pve-usb-nocompanion.cfg:

[device "ehci"]
  driver = "ich9-usb-ehci1"
  addr = "1d.7"
  multifunction = "off"


2) -usb-tablet don't work on ehci with ubuntu
----------------------------------------------
- don't work (mouse not moving) with or without companion
- device is correctly displayed with #lsusb,so maybe it's an xorg driver 
problem.
- It's working fine on windows guest. 




Both bugs result to don't have a working mouse in ubuntu installer.
(vmmouse is not available, and usb-tablet is selected but it's not working).




Any idea ?
