any change if you use "-device usb-tablet,id=input0,usb_version=1" ?

It works.
Comment 4 Gerd Hoffmann 2013-04-02 15:56:34 UTC 
Hans, looks like (some?) windows guests have trouble with the usb2 tablet.
Any idea what this might be?

Hi,

Actually looking at the cmdline this is with a RHEL-6 guest.
 
> Any idea what this might be?

I've run some tests and it is caused by the use of usb-wakeup with our ehci emulation, which does not support wakeup.

I've just send a patch to the qemu-devel list fixing this.

Regards,

Hans
