Hi,
Is Redhat 8.0 supported Firewire or USB2 or both?
If not, Can I config or install some packages for supporting?
Thank you.

I know that there is some kernel support for FireWire. Try (as root) the following:
modprobe ohci1394
I'm not sure about USB2 though, sorry.

Now, I can use "modprobe ohci1394".
I added a harddisk with firewire.
How can I mount it? (mount /dev/??? /my-harddisk)
Thank you.

That depends on how it's seen. You say that you've 'added a harddisk with firewire'... but where did the system see it? Did it think that it was a scsi device? More info please.

I need assistance with this issue too, so here is more info:
my boot.log shows:
Nov 11 18:15:33 localhost rc.sysinit: Initializing firewire controller (ohci1394): succeeded

then I get:
Nov 13 18:01:43 localhost mount: mount: special device /dev/sbp2 does not exist

I added this line below in the fstab:
/dev/sbp2 /mnt/firewire vfat user

so I imagine that's why I get the error, but the later in the boot.log I get this:

Nov 13 18:01:18 localhost updfstab: cannot stat /dev/sbp2: No such file or directory

If I try mount /mnt/firewire I get this error:
special device /dev/sbp2 does not exist


The driver is loaded, but how do I get access to the device!
I checked in /dev/sbp2 and you know what? /dev/sbp2 does not exist! Where do I get such a thing, or am I pointing in the wrong location?

Please end my misery!
I am still learning linux....help!
