+vmmouse device gets attached twice, one without i8042 associated
+Description of problem:
+I'm developing [a driver for the VMware mouse device](https://github.com/NattyNarwhal/vmwmouse). I know this works properly on VMware, but I'm trying it in QEMU too.
+
+[My full notes](https://github.com/NattyNarwhal/vmwmouse/issues/1), but most relevant is:
+
+* a vmmouse instance gets initialized twice (confirmed in qtree), one with i8042 the first time, one without the second time
+* the second vmmouse instance is the one receiving the events, passing them to the i8042 device's fake event handler
+* obviously, a crash because ISAKBDDevice should never be null
+Steps to reproduce:
+1. Load VMware mouse driver
+2. Move cursor (I recommend waiting until Windows loads before doing so, it is very easy to corrupt the guest filesystem if you do it while Windows is loading)
+3. Crash
