the simplest solution to this problem is to add a configuration parameter that specifies vkbd unit number for each entry. this way, the same device (i.e. keyboard) will always use the same vkbd. no more endless cloning. thanks, max _______________________________________________ freebsd-bluetooth@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bluetooth To unsubscribe, send any mail to "freebsd-bluetooth-unsubscr...@freebsd.org"
