I test it with a firewire disk driver, it's a Hitachi 60G 2.5" HDD. When I plug, it just show: fwohci0: Initiate bus reset fwohci0: phy int and doesn't generate any device under /dev. (This disk driver also support USB, and it's ok when I test it with USB. ) Is it because this chipset --Ricoh R5C552-- isn't full supported under FreeBSD?
