udev: recognize USB2, but not firefire.
An external disk can be recognised by udev when connected through USB2, but not when connected through firewire.
In both cases, kernel itself recongises the drive and attaches it to /dev/sda1, (and "mount -t vfat ..." works even when connected by firefire.)
I guess this is udev rule related. But so far, I have not found any clue. I think that any drive attached to /dev/sd[a-z][1-9] should be recognised by udev.....
Any suggestions will be appreciated.
