I've done all my testing so far with XP as a guest, and the -usbdevice 
tablet is working just fine. In fact nothing should have changed in that 
area since builtin devices are synchronous.

I'll setup Linux guest right now and check things out.

Aurelien, can you provide a bit more details on your setup. Do use KQEMU 
or KVM ? Since you mentioned table & mouse I'm assuming that you're 
using a graphic console. Is it VNC or SDL ?. In fact why don't you just 
send me your qemu command like. So that I can replicated the problem better.

Thanx
Max
