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

[Alexandre DERUMIER]

with usb-tablet on ehci:

I  have also look into Xorg.0.log of ubuntu 12.10,

The usb-tablet is seen
(II) config/udev: Adding input device QEMU USB TABLET (/dev/input/js0)

but no driver is found

(II) no input driver specified,ignoring this device


I don't know if something is different with the new usb-tablet for handling 
ehci ?

+ usb-tablet -> vmmouse not loaded + usb-tablet not working

Here some news :

It's not a vmmouse problem, as vmmouse is simply loaded when we move the mouse 
only if it's a PS/2 mouse.



FOR USB-TABLET ON EHCI
---------------------
The problem is that usb-tablet don't work on ehci, so it's not moving

And the default mouse is not the same with or without companion

without companion

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


with companion

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


that explain why without companion, as ps/2 mouse is the default, the mouse 
move and vmmouse is loaded.


FOR USB-TABLET ON UHCI
----------------------
I don't have problem here, usb-tablet is working fine. (But vmmouse is not 
loaded because usb-tablet is the default mouse and not ps/2)



So the problem is :

- usb-tablet is not working on ehci on ubuntu 12.10, centos 6.3,... But it's 
work fine on windows. So is it a linux guest bug ?

- the companion change the default select mouse ???

Thanks, I can reproduce also with centos 6.3



I have also tried to put usb-tablet on another ehci controller, it doesn't work 
too, vmmouse is not loaded

ehci1 + companion
ehci2 without companion + tablet

Maybe somebody known how/when the vmmouse is loaded ?
