Hi All,
I am running sl6 x64.
Question: is there some module I can modprobe at boot
that will get wake up my two Firewire ports? Any
other method?
Many thanks,

Hi Todd,
Mine worked right from the point of installation, but doing an lsmod
shows:
firewire_sbp2 - but nothing using it, but also I don't have any
firewire devices connected right now.
firewire_ohci - same as above.
firewire_core - firewire_sbp2, firewire_ohci - the other two modules
are using it.
I hope that helps & let me know if you need any other info
Regards,
Alex
Huh. Does your firewire plug and play like your USB?
I had a G-Drive Mini (usb and firewire) that I needed to
remove the Apple format. Nothing happened when I
tried it under Firewire. Everything showed up when I
plugged it into my (powered) USB hub. fdisk was
accomplished. It would have been nice to get it to
work under Firewire too.
I see the computer again Tuesday, so I will do an lsmod
on it to see what shows up.
Many thanks,

Hi Todd, Yes I plug it in and it works, and always has been like that.
What I have is a LaCie Firewire DVD-RW unit and also an Alesis
MIDI/Audio interface that both connect no problem, whether hot-plugged
or plugged in before booting.
You mention Apple ( I also use an Apple with SL) so: if it's an Apple
computer (Just to let you know if you don't already) and you want to
boot from you external HDD; it won't. Neither USB or Firewire devices
are supported for booting on Apples (I've tried a lot of things on my
own and most of what I've found on the internet to get that to work Not
even with ReFit will it work - the only thing I haven't tried is putting
an entry in GRUB and seeing if that might do it..but that's a project
for another day...lol). Anyway, only if you have a firewire connection
from another Apple computer will an Apple boot from a drive not enclosed
in itself.
If it's a storage device only, then the firewire sub-system should be
brought up as SL loads, and the device should be visible when the
desktop is up. One other thing is it doesn't matter if it's got an MBR
or GPT (GUID) partition table, but I don't think anything else will work
(again if it's an Apple).
Maybe check your dmesg log and see if there is anything in there
indicating what might be going on at boot time (it should show the fw
modules loading) and also watch the system log when you plug the device
in.
The other thing I was thinking about was packages, since I installed SL
so long ago I can't remember if I added something when I was doing the
install, but from looking at the installed firewire packages in yum, all
the ones I have installed are related to music and dv interfaces so I'm
thinking that anything that was needed for general connectivity was
installed in the default installation.
If it's not an Apple, I'd be checking in the BIOS too, to see if there
is somewhere in there the firewire ports can be turned on and off.
Lastly, if it's a expansion card that's just been installed, you
probably will need to add the modules and/or there could be some
firmware that's needed for that particular device. I'm not all that sure
about that part.
Actually one more thing, if the device and USB ports on the computer are
USB2 and either of your firewire ports are F400 (ie device and/or
computer), then the transfer rate will be better using the USB2. If the
firewire is F800 on both ends, that /would/ give you a faster transfer
rate. You can decide whether knowing that, you want to bother.
Good luck, and just ask if you have more questions when you get back to
it. Sorry this is a bit ramble-ish and somewhat not very well ordered...lol.
Just as an aside; in my experience, you shouldn't have an external drive
routed through a hub, it should be a direct connect to a computer port.
It will work through the hub, but it eventually burns up the hubs ports,
due to the extreme amount of data traffic going through.
