[pve-devel] [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 ?

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 ?
