psiscan видит только родительский девайс.
$ pciscan -v|grep 1394 -A2

Так это не pci устройство.
Это устройства на ieee1394 шине.

Для них база в hwdatabase не ведется.

Чем FireWire хуже USB, по которой база ведется?

Тем, что база по ним ведется ;-)

База по ieee1394 отсутствует как класс.

Более того - устройство должно само сообщать свое имя:
# cat /sys/bus/ieee1394/devices/fw-host0/0040ca0126000494/vendor_name_kv
