Today I find another question in firewire. 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?
