From 21635e121ae0f0ab7874152a7c2f96e9d8cd642f Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 9 Aug 2011 12:35:57 +0200 Subject: usb/hid: add hid_pointer_activate, use it HID reorganziation broke the usb tablet in windows xp. The reason is that xp activates idle before it starts polling, which creates a chicken-and-egg issue: We don't call hid_pointer_poll because there are no pending events. We don't get any events because the activation code in hid_pointer_poll is never executed and thus all pointer events are routed to the PS/2 mouse by qemu. Fix this by creating a hid_pointer_activate function and call it from usb-hid when the guest sets the idle state.
