If HAL is restarted, the device list is sent to the server again, leading
first to duplicate devices (and thus duplicate events), and later to a
FatalError "Too many input devices."
dev->config_info contains the UDI for the device. If the UDI of a new devices
is equal to one we already have in the device list, just ignore it.
