Hi,
I'm reopening this bug since it doesn't fix the device permissions for
the auto connect scenario but only for the "connect before domain start"
scenario.
It is even worst: my VM does not start at all since 0.7.5-4 if my USB
product is not available when I start it (and generally, my USB printer
is poweroff when I start my VM (dhcp server, cups server, ...)).
In /var/log/libvirt/qemu, I got :
LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
HOME=/ /usr/local/bin/qemu-kvm -S -M pc -enable-kvm -m 256 -smp 1 -name kooot

I recall you that /usr/local/bin/qemu-kvm is only a wrapper that change
-usbdevice host:03f0:5b11 into -usbdevice host:auto:*.*:03f0:5b11 before
invoking /usr/bin/kvm
It seems that, with the patch you added, the VM cannot be started at
all if USB products describe in the config file are not here.
To workaround this problem, I removed any reference to my USB printer
in the XML config file (so libvirt does not know anything about it and
so it do not try to find it when starting the VM) and I modified my
wrapper to add the whole argument "-usbdevice host:auto:*.*:03f0:5b11"
when I start the good WM.
In my use case, 0.7.5-4 is a regression from 0.7.5-3.

Vincent
PS: 0.7.5-4 and 0.7.5-5 behave the same way wrt this bug.
