USB/FireWire Ports Issue

So before I go into the apple store and ask for this computer to be repaired/replaced, I would like to see if anyone knows if something can be done about this issue I have pinpointed..
Basically when I have more than a few USB/FireWire ports connected, one or more of the devices does not function properly. This has happened with two external hard drives - which should have no problem being connected simultaneously.. When I try to eject one of them, I receive a message stating that it cannot be ejected because one or more programs may be using it.. although all programs are closed, causing me to have to force eject..
Also, I plug in one drive and open the other in finder to back it up, and all of the folders in the drive are suddenly empty.. nothing inside. I go to Get Info.. Zero KB.. I try ejecting, but receive the same message, so I force eject, plug it back in, and wala, all the files are back in the right place..
This has also happened in the past when my cinema display and a printer were plugged in simultaneously.. the computer won't detect the USB of the cinema display -- which only means that the speakers of the display won't work + no brightness control from the keyboard.. so i let it slide.. but now with this external hard drive issue, i need to solve the problem..
Thank you for reading..

Same here. Since a few weeks, my MacPro ejects USB HDD's as soon as I write or read data on it.
(no I haven't installed something new at this time and all HUB's and HDD's have their own power supply, and yes they have been exchanged, so its not a broken cable or so !!!!!!!!)
After a reset of the NVRAM and PRAM its better for an hour or so, then starts to eject again. I've seen a lot of communities with exact the same question, but never a solution for it. There is also nothing in the support tab of apple.
Hope someone here can help me out or due to the fact that this is a AplleSupportCommunity, a Apple-Employee may starts to do his job and help this huge amount (I guess there are hundrets or tousand) of mac-user with exact the same problem....
btw: don't agree with MACATTACK2010 that this is a hardware problem, cause there are a lot of people in the
net that ask the same question with brandnew Hardware. I think it's an OS or an Update Bug, or may both.

Older ACD USB/Firewire ports and a Thunderbolt MBA.

I have an older Apple Cinema Display (20) and a Thunderbolt MBA. Can I use the Firewire ports on the ACD if I use a Thunderbolt to DVI adapter?
Specifically, I have an older iSight external camera (Firewire based) that I would like to use with the ACD whilst the MBA is in clamshell mode. With the Firewire ports on the ACD, I'm intrigued by how I might access them with the MBA.
Is this possible?
TIA,

Are the USB/Firewire ports powered?

I have an external hard drive that is powered by the USB of my powerbook- and I noticed that the 20" display features usb and firewire ports.
Are they self powered? (the spare ports on the apple keyboard are not- i.e. yu can't charge ipod from them)
Any advice is appreciated
Thank you

The official specifications say:
<< Two-port, self-powered USB 2.0 hub, two FireWire 400 ports and Kensington security port >>
So the USB hub should be self-powered. However, from my experience, connecting the iPod (or any other bus-powered USB device) to the display doesnot work as expected.
Maybe it's because I have all four ports (USB and FW400) occupied, and one of the FW devices is also bus-powered.

Additional USB/FireWire ports

Is there anything I can use to get additional USB and/or FireWire ports? (Such as a splitter (of sorts) or like an electrical strip (WHere you plug it into 1 outlet and gain x # of outlets)?
Thanks

USB, Firewire ports not being recognized?

Recently, I've been having trouble using my USB and firewire ports. I have a 1TB WD external hard drive which has been working fine until about a month ago when it stopped being recognized when I connected it through Firewire. I thought maybe my firewire cable or port was bad so I tried hooking it up through the USB port and it still didn't recognize that it was connected. After playing with it for a while, I finally got it to back it up.
Tonight I connected a thumb drive and it is not being recognized either.
Both ports are being recognized it Disk Utility and in System Profiler, and the USB ports work when I use them to charge my phone and Ipod all the time.
Any suggestions?

Well now I feel a little silly..
I have tried using it on another computer and it was recognized just fine.
However, I have not tried manually mounting my WD hard drive and when I went to try to that, it worked just fine right away, without doing anything.
I then tried the thumb drive again and when I tried to mount it, it came up with this error:
"The disk “UDISK” could not be mounted.
Try running First Aid on the disk and then retry mounting."
So I ran First Aid and it came up with this error:
"Disk Utility stopped verifying “UDISK” because the following error was encountered:
Filesystem verify or repair failed."
The details say that the "File system is left marked as dirty."
So I guess there must be something wrong with the thumb drive, although it seemed to work fine on my PC.

How to fix a lack of enough firewire ports issue?

I am using garageband with an Alesis iO14 audio interface. Just bought a Liquid Mix 16 with a firewire connector. Am having trouble with the Liquid Mix after installation. The mfr. says I should not daisy chain the two. They recommend a firewire expansion card. Is this even possible with the mini? any advice on how I can fix this? I really want to use this Liquid Mix. Thanks.

You are out of luck. This is so annoying. I just don't understand why Apple can not give most of their machines not only two firewire ports, but two independent busses as well. This is not a luxury in my opinion. The only machine in their entire product lineup what allows for expansion of firewire busses/ports is the giant Mac Pro. Mac computers are used in so darn many professional industries that depend on not only fast harddrive interfaces, but interfaces of various kinds that need a dedicated high speed buss. Pro machines should feature pro inputs and outputs. They've even taken the ExpressCard interface away from all but one laptop. What's next? Maybe they should just remove the USB ports too and assume that we all love wireless keyboard/mice/card readers/printers...it's insanity.
You are supposed to be able to daisy chain an enormous amount of firewire devices, but in reality, that just does not work all the time. I too had all kinds of problems chaining a MOTU 828mkII and one single harddrive on one FW buss. No matter of changing order of hooking them up, to which one to turn on first had any effect. They both wanted more than the single buss could give.
I'd return the LiquidMix if you can...the only mac in the current line that I can honestly call Pro is the Mac Pro tower. The others just don't have pro or even semi-pro in/out anymore.
It's almost like Apple really likes to not give us pro's what we really need. Close, but not quite. Imagine a macbook pro with two firewire busses? WOW! The audio and video crowd would go crazy for them. Imagine they also put back expresscard slots on all laptops in the Pro line? You could have 3 separate input busses for harddrives, cameras, audio interfaces, etc. Now that would be pro.

Firewire Port Issue

Hi everyone. I'm a mac person in training and have a question about a machine that I am working on. I had a customer that had a bad front panel board on their G5. Everytime I plugged a usb or firewire device into them nothing would happen. I replaced the front panel board and tested the ports before returning the system back to the user. After I reinstalled the machine onsite, I plugged the users Firewire drive into the front panel board and attempted an Option Boot but only their internal drive would show.
I then unplugged the customers cinema display firewire plug from the back of the system, plugged their firewire drive into the back port and tried Option boot again. This time the drive was found. Out of kicks I tried it again in the front port and it worked there. As soon as I plugged the Cinema displays plug back into the back firewire port, option boot could not find the firewire drive again.
Any suggestions?

irishpunk-
Yup. Happens all of the time.
The FireWire hub located in the monitor is bad. If the monitor is under warranty it can be fixed that way.
I am not a fan of combined devices, as when something like this happens you lose the use of the monitor while the 4 dollar hub is repaired.

Curve 8330 usb/charging port issues.

My 8330 just started to have problems with its usb/charge port. I plugged it in last night before bed like I always do, but when I woke up it hadn't charged a bit and wasn't even recognizing that it had been plugged in. I tried my USB data cable as well, and that didn't register either unless I wiggled the cord around and held it still once it did register. I eventually did get the phone to register that I had plugged it in, but I had to wiggle the cord just so and leave the charger half-way plugged in once I found the sweet spot.
It is a few years old and pre-owned, but this problem literally just cropped up. I haven't dropped it recently, and I only plug it in once a day. It has no problem holding a charge, but getting it to register the cord is a battle. Do I need to just replace it or is there a way to fix this? There are no other problems, just the port acting up. Thanks!

You can try contacting Sprint for repair options for your device.

USB/Firewire port system causing sleepless monitor, lockups

After long last, I finally have figured out why my monitor will not stay sleeping - after unplugging both the USB as well as the Firewire connections from my MacPro, all was well. (Previously, the monitor would only sleep for about 10 seconds, and come back on, or simply lock up the computer all together.) Unfortunately, this means that I can no longer adjust my monitor brightness with the F14 and F15 keys - but, oh well.
Any ideas? Will my monitor require a trip to the Genius Bar? If so, would the cost be prohibitive?
Thanks all in advance!

Here is my recommendation on shopping list and brief tutorial.
Try setting up a couple new hard drives.
Pull the old one for now at least.
Drive #1 main system
Drive #2 600GB backup, 35GB emergency system
Drive #3 data, media files and libraries
Drive #4 scratch if needed, and TimeMachine
Buy SuperDuper or use Carbon Copy 3.3
Buy Alsoft Disk Warrior or another top utility for disk and system maintenance and repairs.
Your current hard drive is corrupt to the point you can't boot from anything or do anything. So the directory and catalogue and probably journal file are "shot" and can't repair itself. May also have bad sectors.
USB modems I know don't work well if at all in Mac OS.
USB cables can cause shorts or electrical anomalies, more often seen as a kernel panic
Instead of the monitor, why not direct USB port? or off your PCIe USB card that it sounds like you added?
When things are "normal" is when you want to make a backup image and keep it for safe keeping.
An actual disk image; a volume image or clone.
A "working" backup with the latest changes.
An emergency system partition that you never use except for maintenance (make a backup image of it too for safety)
Run Disk Warrior etc on a regular basis before there is trouble as preventative maintenance
The Sprint USB broadband replacement I'll leave for someone else that knows what works that you can install.

Usb firewire port usage, connection to light burns

hello everyone. so i went ahead and purchased and received my 23-inch. now its been about a week, in which time friends have come by, and commented on the display, with one comment sticking out and lingering about in my mind.
the ports in the back, figuring that's what they're there for, i use them, for my mouse and keyboard, and from time to time i'll more than likely use the fw400 ports as well. now in regards to the comment made, is it at all possible that my using of the ports, electricity circulating and such, could in time lead to light burns or other on the opposite/front side area of the display?
thank you all.

Between the ports on the back and the display panel on the front there are backlight tubes and a metal reflector. There is no way the plugs in the back can affect the display at the front unless you use a very large hammer to get the plugs in.
Normally, the keyboard is plugged into the display, and the mouse into the keyboard. That way you have a spare USB 2.0 port available on the desk for iPods, card readers, etc. The keyboard port are only USB 1.1

USB/ Firewire Ports not recognized...

Monitor turns off when connected to USB or Firewire port

I just purchased a used Mac Mini Core 2 Duo and have a 20" Apple flay display with USB & Firewire ports. When I connect either of the USB or Firewire cables from the display to the Mac Mini, the display goes off. Is this some kind of short? Or is there some setting that causes this?

USB 2.0 Issues with KT3 Ultra2 6380E

Windows XP SP1
Bios: American Megatrends Inc. 07.00T
Hi I was wondering if someone could help me?
My machine has six USB ports. (1&2) Two ports are
installed on the motherboard, and my users guide says
they are legacy ports. (3&4) two ports are installed
on the d-bracket 2 connector: JLED, connected to
JUSB2, these are what I believe to be my only 2 USB2.0
ports. (4&6)Finally 2 ports are connected via JUSB3 to
the front panel of my Antec case. I think the front
panel of my case has 1.1 connectors so it is
essentially a 1.1 port.
I am having some difficulty getting my USB ports to
function properly with a USB 2.0 Buslink hard drive
UII-40 72E. I suspect there is some IRQ conflict.
Trying to alleviate this I disabled all the device
drivers I suspected might cause this in the device
manager in safe mode. I then removed from the device
manager all the USB (2.0 and 1.1) root hubs, and after
that their host controllers. I then booted to VGA
mode (thinking this should disable the video card
drivers??) and exported this IRQ info from my sys info
after the USB host controllers are reinstalled:
Resource   Device   Status
IRQ 9   Microsoft ACPI-Compliant System   OK
IRQ 11   RADEON 8500 SERIES    OK
IRQ 21   VIA Rev 5 or later USB Universal Host
Controller   OK
IRQ 21   VIA Rev 5 or later USB Universal Host
Controller   OK
IRQ 21   VIA Rev 5 or later USB Universal Host
Controller   OK
IRQ 21   Standard Enhanced PCI to USB Host Controller   OK
IRQ 0   System timer   OK
IRQ 8   System CMOS/real time clock   OK
IRQ 13   Numeric data processor   OK
IRQ 12   PS/2 Compatible Mouse   OK
IRQ 1   Standard 101/102-Key or Microsoft Natural PS/2
Keyboard   OK
IRQ 14   Primary IDE Channel   OK
IRQ 15   Secondary IDE Channel   OK
IRQ 6   Standard floppy disk controller   OK
Next I attempt to (already plugged into D-Bracket
port) power on my buslink USB 2.0 hard drive. As soon
as I do the machine immediately goes to a blue screen.
No messages given but numbers are shown. I have screen
shots taking with my digital camera. I then returned
to safe mode, remove the USB drivers as I did before,
and boot to VGA mode. Once the USB drivers have been
restored I attempt to power on the bus link hard drive
this time plugged into the onboard legacy ports. I
can I get another blue screen this time including a
message "IRQL not less or equal", again I have taken
screen shots with my digital camera.I then returned to
safe mode, remove the USB drivers as I did before, and
boot to VGA mode. Once the USB drivers have been
restored I attempt to power on the bus link hard drive
this time plugged into the front panel USB ports
(4&6). When I power it on Windows XP warns me that I
have a high-speed USB device plugged into a non
high-speed USB hub. But I receive no error messages.
However I do not exceed the drive through "my
computer". I go through the add hardware wizard to try
and at the drive manually and it says the device is
working properly. Still I do not see the drive.
Finally I tried installing a Buslink USB 2.0 PCI card
after the above steps. I then returned to safe mode,
remove the USB drivers as I did before, and boot to
VGA mode. Once the USB drivers have been restored I
attempt to power on the bus link hard drive this time
plugged into the PCI card. The drive seems to be
recognized automatically by Windows XP however my
system slows to a crawl trying to access any hard
drive. When I try and access the USB 2.0 hard drive I
get a message something to the effect of "(the drive
letter) not being recognizable".
Any ideas on what could be causing this? The same
Buslink hard drive works great at work on my Windows
2000 machine plugged into the same PCI card using the same USB cable and power supply. Would any other information be useful?
Thanks!

I first tried installing the VIA4in1 and VIA USB2.0 patch. Then I tried the D-bracket after refreshing the usb drivers (I did not disable all other devices like in my original post, should I have?). Same result, blue screen crash at power on.
Next I disable USB ports in BIOS and install USB PCI card. Then power on the USB HD plugged into card. Same result. Computer slow accessing local drives. When I try to access the USB drive I get a "E:/ is not accessible; the file or data is corrupted or unreadable."
Next I remove the USB card. I enter BIOS and set to "2" ports. Presumably this turns on the USB1.1 ports on the mobo. I return to windows xp. It now seems to install the drivers, but just as it finishes I get a "a problem has been encountered instaaling this device (it has done this before but after finishing I get the blue screen most times). Next I goto the device manager, and in my USB devices I have a USB mass storage device w/ a yellow flag. I goto properties and see a:
"the device cannot start (code 10)" device status. I click "troubleshoot" and voila... blue screen.
Finally I reboot, and set 4 ports in BIOS, making my JUSB3 FRONT PANEL usb1.1? ports active. Interestingly these respond like the PCI card. Computer slow accessing local drives. When I try to access the USB drive I get a "E:/ is not accessible; the file or data is corrupted or unreadable." As soon as I power off the USB HD things are normal...
I will take this USB HD to work tomorrow just to ensure its integrity. Any other ideas? What kinds of BIOS settings might F up USB?

How can I tell if my firewire port is faulty?

I recently cannot import video from my canon elura 100 which connects using a 4-6pin firewire cable. I thought maybe it was the cable so I grabbed my brother's black macbook and it seems to import fine, it still isn't 100% smooth like I think it should be but when I plugged the camera back into my black macbook, the video that was being imported just kept freezing and it seemed warped. I tried this process a few times and kept getting the same results. I feel as though I may have a firewire port issue. How could I check on my own. I know that when I use my firewire 410, I have no problems so I don't know what could be wrong. Any help?

Did any of your problems start with Snow Leopard, is your brother's machine running the same version of SL.
Over in the audio forum there are those having some problems with their firewire interfaces. (glitches, static...etc)

USB/Firewire expresscard

So I noticed today that I was running out of USB/Firewire ports on my 15" MBP. More then that I noticed that I lacked Firewire 800.
I was wondering if there was a firewire 800+USB 2.0 express card, or maybe a firewire 400+USB 2.0 express card that was compatable with my mac.

Check this out:
http://www.siig.com/product.asp?catid=128&pid=1081
SIIG offers a couple firewire expresscard solutions.
This specific one is compatible with Mac OS 10.4.x or later.
Take care
