umsX character device returns a read error. Update devd.conf rules
to use "DEVFS" events which are generated after that the umsX
character device node has been created/destroyed, and then there
should be no need for moused to wait up to 10 seconds for umsX to
be ready. Opening umsX should not fail except if the kernel is low
on memory. In that case the user can replug the USB mouse or use
"usbconfig" to reset the device. In case of USB mouse devices,
moused should neither retry to open its character device,
once the first read error has happened. This is an indication
of device detach.
