How long are the delays for you? > What happens when the (device, bus) is suspended? Does host still > sends interrupts periodically (but with much lower frequency)? Or > is it the bus/hub/device which should signal attention at some point? UHCI raises an IRQ, guest restarts USB bus in response. Which takes a bit of time, so the first mouse event of an idle tablet takes a little bit longer. As far I know linux schedules the first poll a bit in the future, so this could be where the delay comes from. Do you also see delays with xhci? (-device nec-pci-xhci -device usb-tablet) ? cheers, Gerd
