Firewire bus stopped working

Hello
This afternoon my iMac G5 firewire stopped working. I was using seven firewire drives and one firewire audio interface a MOTU 896. I have used this config for about three months with no problems. I was in Reason and then I booted Logic pro (also used IAC rewire between the two programs before) that's when the fun started. Logic froze on mid-boot. Then reason locked up as well. At that point on reboot my iMac no longer saw any of my firewire devices.
System Profiler shows nothing on the Firewire bus.

This appeared in MacFixIt yesterday:
+MacInTouch Reader+
+I have a three-year-old iMac G5 that had a problem since I bought it that I've only just got to the bottom of - its fans would start up (loudly) about thirty seconds after I shut it down. Nearly every time. I think I disabled it from going to sleep pretty soon after I got it, but I vaguely remember it not recovering from sleep and the fans coming on randomly. Eventually I also developed a power supply problem where the Mac wouldn't start up first time, and when it did start up would then switch itself off with no warning (replacing the power supply did fix that problem, at least).+
+Anyway, to cut a long story short, the problem with the Mac crashing (effectively) on shut down followed by the weird, random fan-coming-on thing, was only solved when I replaced my USB (D-Link) modem with one that uses Ethernet instead (a Netgear DG834).+
+I just want to spread the word. It drove me insane for three years and now I'm finally happy. I know my particular, specific problem was weird and maybe quite rare, but if you're using a USB modem with your iMac, maybe borrow something different from a friend for a while and see if it helps.+
The firewire problem may be due to faulty RAM, try running Rember and see if that finds any problems.

Firewire suddenly stopped working

Hi,
In my office we 're editing movies and recently I got a strange problem, the external drive couldn't be found! I tried many cables and nothing will do. I plug it into another Mac and it worked perfectly.
Is there a chance the firewire got blast and how to get it fixed? any solution with OSX?
this is a G4 mirror doors 867mhz with 10.4 on it and final cut pro 5...

Firewire has stopped working - help!

I have 11 iMacs in an education suite. All are the same model and age and have the same set of software on them. Two of these machines are having problems with the firewire ports in that they won't recognise any connected devices including DV video cameras, audio interfaces, external HD's or indeed other iMacs (when started up with cmd T).
All machines ate 20 inch screen dual 1.8 intel core duo machines with 4 GB RAM
Does anyone know what might be causing this or how to rectify the problem
thanks

FireWire ports are prone to failure if the user is constantly plugging and unplugging devices on-the-fly. I had a FireWire port fail on me, but fortunately, it got fixed under AppleCare. This issue is documented on various web pages (you can use Google on "firewire port failure"), including this one.
http://www.wiebetech.com/whitepapers/FireWirePortFailures.php
One thing you can try, if you have not already, is to reset the SMC (power management)
http://support.apple.com/kb/HT1543
I use a self-powered FireWire hub for devices I connect and disconnect often and on-the-fly, such as an iPod or video camera. I might still blow a port, but it will be on the $30 hub and not my Mac. I use the Mac's other direct FireWire port for my external drive which is almost always connected. If I ever need to disconnect it, I power off the iMac before disconnecting.

Firewire stops working

I have updated 3 - G4 733mhz , 1 Mac Mini and 1 17" flat panel Imac with the newest 10.4.8 and security updates. The Firewire has stopped working in all of the above. Any help or suggestions?
(Yes, I've wiped and did a clean install and zapped the PRAM on the 733 and the 17" Imac)

How do you know?
What I mean is, you say "the Firewire has stopped working", but you don't say how you came to that conclusion. Have you tried a variety of devices which are known to work on other machines?
If you have just one Firewire device, that device may have failed (coincidentally). If it is something other than a DV camera or a hard disk, it may require an updated driver for use with 10.4.8.
With your firewire device(s) connected, can you see them in System Profiler? If they show up there, but not in the application, you don't necessarily have a Firewire problem.
Sometimes, Firewire ports apparently "die". Try turning off the machine, unplugging EVERYTHING from it, waiting 10 minutes, then plugging in everything again. This is unlikely to help you if your problem is apparent on 3 machines.

Firewire stops working suddenly

I'm using an iPod Photo, most recent versions of iTunes and iPod software. Took the iPod on a plane to Canada. When I arrived, the library was gone. It still showed that there was 20 gigs on the iPod, but it was as if factory default settings had taken over. Have since restored ipod, recopied library. problem is: now iPod will charge by firewire (plug icon appears), but iPod will not sync via firewire. It acts normally using the usb cable, but as I don't have usb 2.0, it is really slow and annoying and I want to go back to firewire. What is happening? Any ideas?

Stumped: PM G5 FireWire Bus--Unable to list FireWire Devices

I have a nearly four year old Power Mac G5. My firewire ports were working fine a month ago before 10.5.8. Today I went to hookup my video camera to download some tape into iMovie '09 and it did not recognize the camera. A quick check of system profiler:
Warning: Unable to list FireWire devices.
I have tried the following to fix in this order:
1. Reset Pram (commandoption+PR)
2. Reset Devices by (commandoption+OF)
reset-nvram
set-defaults
reset-all
3. Repaired Permissions
4. Reset PRAM
5. Reinstalled 10.5.8 combo installer
I still cannot get the firewire bus to work. I am open to ideas. Someone suggested removing the PRAM battery but I have been unable to figure out how to do that.

I ended up unplugging computer for 5 minutes and re-plugging in and this seems to have solved problem (although I do not know why.)

Firewire stopped working on iMac G5

I have 2 firewire external drives on my iMac G5. Today, after a reboot, they stopped showing up. I moved them over to another mac and both came up just fine, so I'm sure the drives and external cases are good. I then connected one using USB (the other one doesn't have USB). It's working ok with USB. The problem is I need Firewire for other stuff (video camera and other camera hook up), plus I prefer to use firewire for the external drives.
When I go to System Profiler and click on Firewire, it shows "Firewire bus:" and that is it. Any ideas? This it a bad logic board? Is it possible that the firewire circutry got disabled? Can I fix it? Any suggestions would be appreciated.
Thanks!

Try one of these:
Zapp the P-RAM:
After the startup tone, hold down <commandd><option><p><r> until 3 additional startup tones are heard, then release the 4 keys.
Open Firmware reset:
After the startup tone, hold down <command><option><o><f> until the text screen is visible. When text can be entered, type the following commands, followed by the <return> key (there are no space characters in each command):
reset-nvram
set-defaults
reset-all (the Mac will boot up after this command is entered)

IP over Firewire stopped working

with the 10.5.2 update IP over Firewire stopped working. I tried this with 3 machines on my G4 server (still running Tiger) and 2 different Firewire cables. target disk mode still works, so it can't be the cable. I'd appreciate any input & ideas.

I figured this out. Shut down for 20 minutes or so. Turned the Macbook on and firewire IP workd.

My Apple desktop computer, 2.4 GHz Intel duo core, OS 10.6.8, stopped recognizing the WD My Book connected via firewire. It works fine with the USB port so it's not the drive. Help please.

My Apple desktop computer, 2.4 GHz Intel duo core, OS 10.6.8, stopped recognizing the WD My Book connected via firewire. It works fine with the USB port so it's not the drive. Help please?

It can be the bridge. It could need firmware update. or the FW ports may be an issue. LaCie seemed to invent the phrase/tip 'resetting firewire ports' due to the issues with their drive cases.
You can try an SMC Reset.
So far I have avoided name-brand and tend to see them mentioned. Often with a new OS (though you are on 10.6.8, but when 10.6 came out there was a common complaint and thread of users: FW or USB worked but not the other interface).

Firewire stopped working

My Firewire external hard drive and DVD burner have recently stopped working. Actually, I'm sure they work fine, but I can't connect them to my computer. I recently moved, and before the move everything was working fine, and after the move my computer wouldn't recognize anything I connected to it via Firewire cable. The external drive is 150GB from Acomdata, which I've had for roughly a year; and the DVD burner is from LaCie, which I've had for two weeks.
The external drive has a USB port in addition to a Firewire one, and it works if I connect it with a USB cable. But the DVD burner only has Firewire ports on it. I know the burner isn't broken, because a light comes on when the power source is plugged in.

One thing to try is to turn off the iBook and remove the power adaptor and the battery and let it sit for 30 minutes or so. Sometimes the ports "reset" if you do this.
Good luck!

NJ3 - Firewire stopped work

Hi,
the firewire port of my trusted Jukebox suddenly stopped working. I was in the middle of uploading some files when suddenly the player froze. Since then I have not been able to transfer any songs via firewire to the player - neither by using the Notmad Explorer nor by using Media Source. The tranfer starts but suddenly stops or the player freezes and there is nothing transfered to the player.
Resetting, rebooting, cleaning up, reinstalling the latest firmware all have not helped.
USB still works (but of course very slowly).
Has anyone have had any similiar problems?

Only those with faulty firewire ports I would think. If you want to get it repaired you'll have to contact support. I assume you've checked with another cable?

Right USB Port stops working after disconnecting device since 10.9.2

Hi,
Since updating to 10.9.2 the right USB port on my MBA stops working after diconnecting a device (tested: external hard drive, USB flash drive, USB HSPA Modem). The only way to get the port recognizing the device on that port is to do a restart. If the device is connected from starting the MBA it works fine, if I then eject the drive and reinsert it or a different USB device the device doesn't get recognized. The devices do get power, my WD passport ultra spins up just fine, the USB HSPA modem also indicates it's working (with signal) but nothing shows up in finder or diskutility. If the modem is connected from start (and thus working) and then disconnect from the internet but not remove the drive I can reconnect to the internet. The problem only occurs after disconnecting the device. The port becomes inactive. The left USB port works as expected.
Steps I've taken:
Disk Persmission

SMC

Nothing out of the ordinairy. Thanks for any help

It's an Apple Pro keyboard and mouse, the dongle is
plugged into the Mac and not the keyboard. The same
set-up is, and has been working on all our other
Macs.
The sleep issue sounds interesting- hum, maybe...
Is your keyboard plugged into one of the USB connections on an Apple monitor? If so, you may want to change that connection to one that is on the G5 itself. My monitor came with a warning note indicating that problems will likely occur if the keyboard is connected to the monitor.
I also had a problem with the automatic sleep function. After much trouble-shooting and a logic board replacement, it was concluded that coming out of the automatic sleep function with any USB device active would freeze the entire USB bus. After disabling automatic sleep in system preferences, I've had no freezing problems. My machine works fine with the manual sleep function in the Apple Menu.

Same exact thing with me. And no help from apple. Just dropped nearly $600 and cannot get a decent working setup.
Apple's only suggestion was to uninstall iTunes and Quicktime, and re-install... of course (the I.T. Crowd tactic).
The crash happens only on iTunes store access.

Thunderbolt camera stopped working with Skype and Google Hangouts

Some time ago my built in camera on the thunderbolt stopped working with Skype. If I activate the camera the green light turns on but the screen either remains black or it shows that spinning loading incon forever. The green light stays on indicating the camera is active no matter what I do with skype even if I press the button to deactivate the camera. The green light remains on until you completely kill skype. Rebooting, reinstalling skype, etc. does nothing.
Today I disocvered I have the same thing with Google hangouts. All the way around exactly the same and the green light won't turn off until you kill the web browser. Same thing with FireFox or Safari. Also it no longer works on Viber either.
It's quite infuriating.
I am not sure if this has anything to do with this awful virus like program called "CamTwist" that I installed once and had a very difficult time removing or not.
Reinstalling OS X from scratch is not an option. Too much work, too many programs to reinstall and reconfigure etc.
How can I get my camera back?
The camera works just fine with Photobooth and facetime.
Thanks.

1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
        Part 1 of 8 done at … sec
        Part 8 of 8 done at … sec
        The test results are on the Clipboard.
        Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I may not agree with them.

Firewire Bus Issue

I have a I Mac G5 with 10.3.9 installed and I have had the computer for about 1 and a half years. I have daisy chained three maxtor drives which I okayed with apple support--I wanted to make sure this computer could handle the three drives, and a video converter. About two months I bought the LaCie dvd burner and have to swap firewire ports with the Sony Converter when I want to burn discs.
Everything has worked just fine until about two weeks ago when i couldn't boot up the computer. I took it into an Apple Store thinking it might be related to a power problem I had about 9 months ago. After a two hour diagonostic was run twice on the machine the support people could find nothing wrong with the computer.
It also started up fine without the firewire ports being used and I didn't recognize that this must be the problem at that time.
The next morning, with the firewire cables plugged in directly to the back of the computer it wouldn't start, so I shut down, unplugged everything, waited a few moments and then plugged the processor back in. It started right up.
Now, I understand what's wrong, but don't know how to fix it. When the unit doesn't start up, as it didn't a few nights ago after I burned a dvd, I shut down and unplug the firewire cable and then reboot. I then can plug in the Maxtor drives, etc., and the processor works fine.
So, it seems to be a start up issue with the fire wire bus or whatever.
Does anyone know what I can do to fix this and get things back to the way they used to be?
I don't want to upgrade to Tiger because I have apps that won't work with Tiger and I don't want to upgrade them at present either.
Any help or advice would be greatly appreciated.
By the way, I use the external drives for my film shorts.

This is Apple's article -
http://docs.info.apple.com/article.html?artnum=88338
FireWire ports can (or use to) get "fried" (99% of
the first FW Mac, Blue G3 users had to eventually
invest in PCI FW controller as ports would just stop
working).
I would invest in PCI FW800/400 rather than
daisy-chain and so you have two buses (all the FW
ports share one common bus).
A powered hub has its own a/c.
There use to be more talk about using "isolator FW
cables" to prevent hot-plugging from causing
electrical damage to FW ports.
I am not a fan of most of the vendor supplied FW
cases (Maxtor, WD, etc) and just go with a good
Oxford based unit (FW bridge type) which are more mac
friendly and work. Or even eSATA for hard drives
(SeriTek etc) which allows each drive to be on its
own channel.
Hi,
Thanks for the imput. What do you mean that the powered hub has it's own a/c? I'm confused.
Next time I get a drive I may go with the Oxford based, altho' I have to say that the Maxtor Drives have been very reliable so far.
As for the controller, I have to see if I can get one for the IMac. I got a PCI card for my G4 and that was a help.
I'll check out this article. Actually, I've already read this.
When I took the machine to the apple store they checked my firewire ports. They checked everything and they said when I called today that the ports were not fried, that they were okay.
My question is: why would the computer boot up when I unplug the fire wire cable and not boot up when I don't? this is a new development and I've been fine with this machine for over a year.
