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 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.

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.

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...

My iMac will not recognize my iPod, printer, camera, or anything that is plugged into it. What could be the problem? Thank you so much for your help!!!

Kristi,
Please tell us what iMac model you have. I think the problem you have on this thread:
http://discussions.apple.com/message.jspa?messageID=3021123#3021123
Is related to the one you have here. Here is how to identify iMacs:
http://docs.info.apple.com/article.html?artnum=301724 - G5 & Intel Core Duo (look identical on the outside except when you About This Mac on the Apple menu).
http://docs.info.apple.com/article.html?artnum=301724 - G4 (Dome with flat panel on articulating arm)
http://docs.info.apple.com/article.html?artnum=58669 - G3 (CRT)
If indeed your Mac is not an Intel Core Duo, in the future find the correct iMac forum to post your questions once we resolve this problem. I understand how each of these iMacs work, but I may not be in this forum all the time.

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/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

I have a belkin 7 adapter for additional USB slots for my Mac Pro. It was working well till just recently I am getting a message that says the usb port on the Mac Pro is shutting down due to a very high power drain. Then it shuts the usb port down.

I have a belkin 7 adapter for additional usb ports for my mac pro. It worked fine without problems till recently when the message regarding usb port drawing too much power and the computer shuts the port on the mac pro down. The strip comes with its own power supply adapter. The attachments are additional hard drives used as backups and independent data. Other than disconnecting it are there any fixes?

You're getting the message because you're exceeding the available current, probably as a result of bus-powered drives. The power sources for hubs are rather small. Try using drives with their own power supplies.

I can't sync with FireWire port and I can't charge with USB port!!

Hi. I've a old model of iPod (M9244Y). After the last update, my iPod does sync with the FireWire port.
I tried with another PCs and Mac but it does work. Finaly I buyed an USB cable and this one syncs but not charge.
I've restored to early versions of iPod Updaters but it does not work again. Can I do somethig to fix it?
Why I can't sync with the FireWire port?
Please help me, I can't live without iPod, I can't live without music!!!

Do you have other Firewire devices? Do they work? Could be the FW ports are not working right.
First thing to do is reset the FW chip set on the mother board. Unfortunately, when you power down the computer there is always a bit of power still applied to the motherboard to keep things alive and this usually includes the ports to do stuff like detect when a device wants to wake up the computer. The downside of this is when a bus/port chipset goes into a weird state, power cycling the computer won't work.
So first thing to try is resetting the chipset and to do this you have to power down the computer and completely unplug the computer from the wall power (unplug the power cord to your Mac). Also unplug everything from the Mac's ports (USB, FW, Ethernet, etc.) to make sure no parasitic power is still there to keep the chip alive. Now let it sit for ten minutes (give those big power caps in there time to discharge). Now plug it back in, start up the Mac and see if your FW ports and the drive work any better.

Leopard USB and Firewire Ports

With leopard 10.5.1 loaded, I frequently get the grey screen of death (kernal panic) if I have a USB device plugged in (other than the mouse and keyboard). I have Pantones's Huey (Screen calibrator) attached to the USB on my keyboard. After reading many forum issues about USB devices jamming up Leopard, I decided to unplug the Huey sensor... no more problems! Also I have a 500 GB WD My Book Studio external HD plugged in the back Firewire 800 Port, it works well. Plug a Digital Camcorder in the front Firewire port.. not only does my camcorder not mount, but my machine spits out the external HD and gives me an error message about improper device removal. Please release 10.5.2 and include fixes for these external device issues!
PS on a Tiger OS I have had zero conflict with these periferals

When I first installed Leopard I got an "install media is corrupt" message about the Leopard Install disk right from the start. My first thought was the hard drive. So I purchased and overnighted an new 500 GB internal hard drive to back up the main hard drive. I erased and reformatted my main hard drive to install Leopard on. Same problem. I tried to install on the new 500 GB HD no luck. I also installed 2 GB dimms at the time. Turns out the dimms weren't agreeing with leopard. I returned the dimms for new only to have the same "corrupt media" message. Crucial explained that the memory should be largest dimms toward the processor (slots 1 & 2) and so on. I put all my memory back the way it was and everything seemed normal. I installed Leopard successfully. I started to get frequent Kernal Panics with everyday use (I do graphic design). I checked the forums and kept reading about problems associated with USB and this or that program. I unplugged my Huey (used for screen color correction) and Wha-lah. No more Kernal Panics.
But, now my digital camera and my Dazzle 6in1 media reader do not mount and/or hang up my machine with a kernal panics. When I tried to boot from and use Leopards disk utility I got the "media corrupt" message again.
I just hope 10.5.2 addresses the Leopard to hardware/USB/Firewire issues.

What is wrong with my 30" Cinema Display? The USB and FireWire ports still work, but the screen is pitch black. When you plug it into the computer, it detects that it's a Cinema Display.

When you plug it into the computer, it detects that it's a Cinema HD but the screen is pitch black.
For some reason, the USB and FireWire ports still work.

If you shine a really bright light directly into the screen can you then see a faint image on the screen? If so, that would indicate the backlight has died (hardware failure) and the unit needs repairing.

Need connector from firewire 400 to USB 2 port

got a new i-book and want to use my old ext hardrive firewire 400 for backup.
Is there a cable that connects the new i-book USB port to the firewire 400 ext hard drive so I can use the old external hard drive as backup?
Or am I screwed?

Doesn't the FireWire port on the iBook work?
Or are you mistaken about what you have? Is it a MacBook you have instead of an iBook?
If it is a 2010 Mac, it would be a MacBook, and, yes, it would not have a FireWire port.
External USB drives are fairly inexpensive. That would be the route I'd take.
