Adding USB ports to mac pro

Hi,
i was wondering if anyone knows if it's possible to fit more usb ports in the back of the Mac Pro?
I got my mac pro about 4/5 years ago, and could really use some more ports.
Thanks for any help and advice,
Tom

What's wrong with using a hub?
A few things:
With a hub, all devices must share the bandwidth of the one built-in port the hub is on. If one device on the hub takes up all the port bandwidth, too bad for the others. Or they will fight it out. But with most types of USB cards, each individual port on the card gets full USB bandwidth...no conflicts.
You need to use up a built-in USB port to plug in a hub, so adding a 4-port hub only gives you 3 more new ports in reality. With a USB card, all card ports are in addition to the Mac Pro ports.
A hub needs to take up one more outlet on your power strip. Or two or three outlets if it has a big transfomer. A USB card uses the Mac Pro power supply directly with no additional messy power and data cables.
A hub probably doesn't cost that much less than a USB card, if there is any price difference at all, yet the card has so many more advantages.
About the only reason to not get a USB card is that you've already used up the slots in your Mac Pro.

Adding 400 port to Mac pro quad

what is best card to add a 400 port to Mac Pro? XHA1 will not work via any 800 cable, must plug directly into 400 port. Why was the 400 port dropped anyway?

There are adapters, such as

I still don't know what happened to my test Aperture Library after the update to 3.4...Not only were my previews lost, but so were the original images! Needless to say, I haven't bothered to update the main library on the Mac Pro because I don't want to deal with this level of uncertainty (even with backups in place).

Firewire port on Mac Pro

If I use an adapter to connect firewire 400 to 800 port on Mac Pro. Will entire firewire bus on Mac Pro reduce to 400 speed or each port is independent?

All ports feed into the same bus, but you can run a 400 device from one port and an 800 device on another port and both will operate to their respective theoretical speeds. However, if you daisy-chain FW800 devices into a FW400 device and then to the Mac Pro, all will operate at 400 speeds.

One of the USB ports on MacBook Pro does not work.

Hi,
I purchased a MacBook Pro in Jan '11. Both the USB ports on the laptop were working fine. Recently, I have noticed, any external device connected to the USB port, towards the battery side does not recognize the connection.
Any solutions ?. Is this defect covered under warranty ?.
Regards
Anil Madan

Anil,
Try resetting the SMC.
SMC RESET
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Apple USB modem crashes Mac Pro (MacPro3,1) ???

(1) After plugging an Apple USB modem into one of the rear USB ports of my (new) Mac Pro I get weird crashes (sometimes 2, sometimes 10+ a day; sometimes the grey "curtain" falls, sometimes the machine simply freezes with no other symptoms). Here is an example crash report:

(2) Now, if an Apple USB modem doesn't work, what are my options to send & receive faxes w/ this machine?
TIA, Harald

Yes, this is true. I use a iMac8,1 whit the same symptom. The Modem is used to receive faxes direct to the mac. We use the standart fax software from apple. i can work for days whit out crashes. But then... I wish some one at apple would take care of it...

Selective USB power while Mac Pro sleeps

My Mac Pro seems to power all USB ports during sleep. I would like to selectively power some ports and not others. For example, I have a utility USB light on the back of the MAC Pro and a CwLinux LCD screen on the front which I would like to see turn off whenever the Mac sleeps (The USB power controller gets hot if these stay on for long periods without airflow).
Any thing in Leopard that would control this behavior?
Thanks!

There is no provided mechanism to selectively control power to the USB or Firewire ports. Normally USB ports shut off when the computer is asleep unless you connect a device the prevents the port from shutting down, which you obviously have. You will just need to get used to disconnecting them when not in use if they don't have power switches.

Need help one USB Port on MacBook Pro not working

Its been a weak now and im getting tired of my MacBook pro USB not reading anything.. It wont read/connect usb drives, IPods/IPhones/IPads, and Android phones. I have tried the PRAM and SMC resets and nothing has worked i even left my Macbook pro off for a whole day. ITS ONLY ONE PORT NOT WORKING, i took it to bestbuy because its closest to me but geek squad just did what i explained above and told me get a USB hub and NO! i want to fix this issue... Anyone has had this happen can you let me know if its because the USB port is no longer working or a software issue... Also i keep getting this notification telling me USB devices disabled draining to much power but i have nothing connected!!
ps- my MacBook Pro is getting very hot fast and it happens when im not even using it, i get home and it very hot could there be another hardware failure i dont leave applications open when i sleep it.

It sounds like you might have a hardware problem. Your best bet is to go to the Genius Bar. The evaluation is free, and they'll fix it if you're under Applecare. Back up your stuff first though.

Just one USB port on MacBook Pro 15"

Hi, I just got a MacBook Pro 15" 2.33GHz. I may be silly but I find it has only one USB port! This is killing me because I need at least two USB port to connect my mouse and iPhone. Do I missed something?
Thanks,
ff

Both USB ports are on the left side, right next to each other.
Maybe you have too many things plunged in and you can't see it or something is covering it up. Reminds me of this:

USB Ports on Macbook Pro (Late 2011) no longer working...

Hey all,
I know there are numurous posts on this but none have seemed to help me.
Today both of my USB ports have stopped working. Two months ago the one next to the thunderbolt port would go in and out and today both of them just don't work at all except to supply power. I can still charge my phone with them but thats it, nothing is recognized when I plug it in.
I've tried the PRAM reset, the SMC reset, manual reset, regular reset, updating the OSX to the latest and nothing has helped. I've read I might have to replace the logic board but I really hope I don't have to resort to that.
I've posted the reports from the System Information and an app called Etrecheck. Hopefully someone will be able to pinpoint the issue.

Thanks for the response,
1. I live in Atlanta, close enough to an Apple store. But I just know that going there will probably mean I'll have to get the logic board replaced.
2. The only thing I noticed before the first USB port started acting funny was that my battery status changed to "Service Battery". I plan on replacing it this week too.
3. Nope only difference is that my battery drains kind of fast. After about 3-4 hours of my normal usuage with it (Internet, music, videos, and sometimes using Logic) it will be time to hook up the charger.
Would replacing the battery do anything? I'm not thinking it would but figure it'd be worth a shot since I've got to replace it anyway.
And to goofyziggy,
I too noticed that most people who had this problem had some version of OSX 10.8.x

Display and USB dead, but Mac Pro still running?

Hi,
Two days ago, my 8-core Mac Pro (early 2008) became unusable. It displays the Apple logo on grey background during startup then after a while, the rolling "circle" freezes, yet the Mac keeps booting as we can still hear the hard drive running. Sometimes, the screen blinks once or twice just before freezing, but nothing more.
After a while, the Mac finishes booting up: its name appears in the "Shared" section of a Finder window seen from another Mac. However, I can't connect to it via "Share Screen": error message saying the Mac is unreachable. The keyboard doesn't work either cause I can't blindly use it --not even to try to restart the Mac (CTRL-EJECT + R).
If I plug my iPhone, the battery starts charging but no synchro --I don't hear the faintest noise from the hard drive, meaning iTunes doesn't launch.
However, I can connect to the Mac thru file sharing; once identified, all volumes appear and can be mounted and browsed normally. I also can connect thru a SSH session and pilot the Mac via the Terminal. Note: the "shutdown -r now" command seems to work as the shutting down message appears with three beeps and the Mac disappears from the Shared list mentioned above, but it doesn't turns off "physically"; fans and hard drives keep running and the front LED remains on... forever.
All this makes me think there's something really wrong with the I/O management (except network but is it really I/O?): no display, no mouse, no keyboard (no USB).
Of course, I zapped the PRAM, removed the extra RAM I bought two months ago, I also removed one by one the two internal hard drives and checked all possible connections. The same problem keeps happening during startup, even with only the system DVD in the superdrive --without any hard drive connected, just to be sure.
For information, the very first problem happened while playing a game on Windows via Boot Camp: the screen froze but music and sound kept running. After three restarts --still under Boot Camp-- and a freeze a few minutes after I was back in the game, I gave up and restarted under Mac OS X. The Mac worked normally for about an hour, then crashed while I was browsing my music in iTunes. The next crashes were happening faster after each restart. And now, the Mac won't even boot normally.
Here's my story. If one of you guys have an idea of what could be happening on my Mac Pro, I'll be very glad to read it. I'm not really keen to send it to maintenance for several reasons, one being that after not even two years of age I still consider it a "recent" computer, the other being that with the holiday season coming up, I wouldn't like to see it go away for weeks!
One more thing I'm a freelance graphic designer, I've been working with Macs for more than 20 years and I take good care of my machines.
Thank you for reading.

Hi,
Well, I now can say that that's also what happened to my 8800 GT.
I finally received the ATI Radeon HD 4870 and after I've installed it, I was able to boot the Mac Pro on Windows (I got the PC version of the card so it needs to be flashed before it can be used with Mac OS X) and this time, everything went fine; I tried the games I've had problems with earlier and they all ran perfectly.
I then successfully flashed the Radeon so it's now compatible with Mac OS X and Windows, but I still have a power problem: the card is sold with two Molex-to-PCIe cables whereas only micro PCI-e connectors are available on the Mac Pro. There's the option to use the SuperDrive's Molex connectors but there're only two of them and four are supposedly required (see note below) to sufficiently power the card. This means the picture is scrambled in Mac OS X and when trying to boot on Windows, a blinking power error message is displayed onscreen and booting stops.
Note: in the Radeon manual, it says (with nice illustrations) that the card requires two full PCI-e cables and that Molex-to-PCI-e adapters aren't supported, *although the card is sold with two of these unsupported cables ONLY!* However, before flashing the card, Windows booted successfully with those two cables so I don't quite understand the logic behind all this...
Anyway, I've ordered the missing full PCI-e cable (I already have the one that came with the NVidia card) on eBay (amazingly, this cable is impossible to find in France!) When I receive it, I'll post a final message in this thread to let you know if my problems are now solved.
Thanks for reading =)

How to DIY-repair fried USB ports on Mac mini?

Accidentally I fried (or so it seems) all the four USB ports of a Mac mini 2 GHz Core 2 Duo 2 Ghz 2 GB 160 GB SuperDrive AirPort Extreme Bluetooth (released by Apple on August 2007) with Mac OS X 10.6.8 Snow Leopard. It was after connecting an iPhone AD/DC to power a USB hub.
I can access the machine using a wireless keyboard but the USB keybord or any other USB device is not recognized when plugged into the USB ports of such Mac mini.
I know that I can carry the Mac mini to a repair service or switching the main logic board, but it costs more than the current price of the machine!
I was thinking of some kind of DIY, even if it requires soldering... Any ideas to replace the fried USB ports with new ones?
Note: the USB ports and main logic board seem OK after visual inspection, but I guess that the former are fried since resetting the PRAM and SMC did not work.
Thanks.

DIY soldering repairs are pretty much out of the question.
Most, if not all, IC's that would be related to the problem
are of the BGA (ball grid array) variety and require special
equipment to remove and replace as all the connections
are under the IC.
The only DIY alternative would be to purchase a logic board
and replace it yourself. Just Google "mac mini logic board
replacement" for sources and how to's. Apple themselves,
will not sell you logic boards, so you need to get it from a
third party vendor. As to which ones are are the most reputable,
I cannot really say. I would suggest avoiding any Ebay offers
that are not reputable retailers.
As usual, be aware that if a price on such an item is too
good to be true, it probably isn't.

Adding new RAM to Mac Pro

I just got my new Mac Pro. It comes with (2) 1G sticks of DDR2 RAM. I bought (4) 2G sticks of DDR2 RAM from OWC to put in it. Can I just add my 2G sticks and keep the 1G sticks in, or do they all have to be the same size?
I spoke with 2 different Apple reps on the phone today, and they gave me 2 different answers. One said no - they all have to be the same size. The other said I could use different sizes, but they just have to be paired.
Anyone know what the right answer is?

Hi
my Mac Pro configuration in the system profiler only shows 512MB cards in Raiser B DIMM1 and DIMM2, allthough I have added new 2G cards into Raiser A DIMM3 and DIMM4.
The Raiser A DIMM1 and DIMM2 slots are occupied by 512MB cards as well, but these are also not visible in the Memory Slot summary.
Question: It seems I have 6GB memory, but only 1 MB visible in the Memory Slot summary. Is this possible and how can I activate the whole memory?
