I've also noticed this, I thought it was a multiconfiguration problem, but
even applying the patch suggested sometime ago here, I could noticed the
slowness.
For this I guess the configuration is linux host and windows guest as is
my case. Slowness started once I issued usb_add on the qemu console and
after finding the emulated system unusable slowness stopped on usb_del on
qemu console again.
I think the problem may be the qemu lacks some usb feature, maybe not
implemented yet. But I would be glad of hear what qemu people has to say
about this.
Thanks.
