Isn't the lack of a node name a significant part of the problem?:

udev_rules_apply_to_event: LINK 'lircSerial'
/etc/udev/rules.d/capture-card.rules:7
udev_event_execute_rules: no node name set, will use kernel supplied
name 'lirc1'
udev_node_add: creating device node '/dev/lirc1', devnum=250:1,
mode=0600, uid=0, gid=0
udev_node_mknod: preserve file '/dev/lirc1', because it has correct dev_t
udev_node_mknod: preserve permissions /dev/lirc1, 020600, uid=0, gid=0
node_symlink: preserve already existing symlink '/dev/char/250:1' to '../lirc1'
link_find_prioritized: found 'c250:1' claiming '/run/udev/links/lircSerial'
link_update: creating link '/dev/lircSerial' to '/dev/lirc1'
node_symlink: preserve already existing symlink '/dev/lircSerial' to 'lirc1'
udev_device_update_db: unable to create temporary db file
