One usb port left

My Desktop Quicksilver G4 only has one USB port that is usable. I have a flat screen with 2 ports in the back that never worked and an airport extreme that has a port but I can't get anything to run off of that.
I use the only port I have for my wireless keyboard and mouse. When I go to print, I'm up a creek without a paddle.
What are my options - short of buying a new computer.
Thanks.

Have you ever tried reseting the PMU.? Sometimes that will reset USB ports, unless you fried them.
That article is for a different model G4, but it is the same procedure for yours.

Mid 2011 Macbook Air - Yosemite keyboard and trackpad stopped working, the only button that worked was the power button, only one USB port works.

I have a Mid 2011 Macbook Air.
Upgraded to Yosemite last week.
Three days ago I was using my Macbook Air for the first time since upgrading to Yosemite. I had been using my Macbook Air for approximately 30 minutes, I was using safari and the keyboard and trackpad stopped working (would not respond). The only button that worked was the power button.
I rebooted and they were still not working. I plugged in a USB mouse and external USB keyboard, only one USB port would work (the Left USB port if looking at the screen) so I had to swap between keyboard and mouse.
After logging in there is a bluetooth icon at the top of the screen with a sawtooth line through it. Bluetooth is unavailable and the bluetooth icon is missing from the system preferences menu.
If I run a hardware test by holding D (on USB keyboard) at startup it says that no problems are found and at the conclusion of the test the keyboard and trackpad start working again. When I log on the bluetooth is working again.
I shut down the Macbook Air and when I started it again the keyboard and trackpad and right side USB ports were all not working again. I logged in using the USB keyboard and mouse and the bluetooth not available sawtooth icon had returned.
I ran the hardware test again and at the conclusion of the test the trackpad and keyboard started working again.
I have tried deleting com.apple.Bluetooth.plist and com.apple.Bluetooth.plist.lockfile from /Library/Preferences/ and tried resetting SMC and Power Functions but this did not fix the issue. The only thing that seems to work is running a hardware test - obviously I don't want to do this every time I use the computer.
I do not believe any hardware is faulty/damaged - I think it has something to do with bluetooth/Yosemite.
I do not have the Macbook with me at the moment, if you have suggestions that I can try or additional checks/info you require please let me know and I can get back to you.
Thanks,
John

Hi!
I have exactly the same problem, and I can't find any solution.
I can't even track down the root of the problem: the Bluetooth/Wifi module? The trackpad? The keyboard/top case? The logicboard?
I've tried all the usual: SMC/PRAM reset, clean install, kext cache clearing.
Any suggestion is greatly appreciated!

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:

ITunes said my iPod Nano 4G is corrupted when it's in one USB port, but not in the other.

iTunes said my iPod Nano 4G is corrupted when it's in one USB port, but not in the other. Is the port faulty? Windows 7 PC

Could just be a loose connection or that the cable itself is going bad. There are a number of factors that could play into this scenario.

How do you connect a usb printer and usb external hard drive to the airport extreme, as it only has one usb port?

I'm thinking about upgrading my old 802.11g router for a new airport extreme. Can it connect to a usb printer and external hard drive at the same time and acutally work. It only has one usb port on the back.
thank you!

To add multiple USB printers and/or HDDs, you just first need to connect a USB hub (powered prefereably) to the AirPort's USB port, and then, add the USB devices to the hub.

One USB port isn't working...

Hey,
I just realised that one of my USB ports isn't working when I plugged in my mouse... Should I be very concerned about this?
I live in a really remote community (ie no stores anywhere closer than a 3 hour plane ride away) and can't bear the thought of living without a computer for several weeks if I send it to Apple to be repaired.
Could it be a sign that there's something else going on? Is is expensive to fix?
Thanks!!

Welcome to the Apple discussions.
When one USB port isn't working, often a Power Management Unit (PMU) reset will fix it. Follow these directions: http://docs.info.apple.com/article.html?artnum=14449

Using more than one USB Port at a time?

So, I'm trying to record something in a project using my Rocksmith USB to 1/4 inch cable, but I also need to make a screen recording of me doing that for a school project using my RockBand USB mic. The problem for me is that only one USB Port recognizes these two, and the three that don't aren't dead, as they work with everything else I have. How do I set it so that more than one USB port can recognize these devices? I don't want to have to keep switching every time.

Thanks mhartnett.
I have looked at the example on the link you gave. According
to the example for the FileReferenceList in the documentation, it
seems to make multiple or rather separated requests to the
server-side upload script.
So for example if I have 3 files to upload, the script will
call the the upload() function of the FileReference class thrice
with the URLRequest(which is the server-side upload script). So in
this case, my server-side script that is handling the upload will
only upload one file at one time.
Is there a way where I can have say all the 3 files sent
together to the server-side script, and then have them uploaded all
at once within the server-side script itself?
So say my PHP file, I could have access to like
$_FILES['Filedata1'], $_FILES['Filedata2'] and $_FILES['Filedata3']
together at one request.

Mac pro late 2013 one usb port doesn't work

Hello there, I've purchased a used Mac Pro (4 cores, late 2013), and seems like one USB port (lower right) is dead, the rest work fine.
Things I tried:
1. Fixing disk permissions.
2. Resetting NVRAM/PRAM.
3. Running Apple diagnostics (Holding D / Holding Cmd+D during startup).
Nothing helped. What do I do now?

When you plug something in, go to the System Profiler (Apple menu, then "more info"). Does it recognize whatever is in the USB port? Could be a driver issue...

Random Errors fix one another pops up - One USB port won't install device's drivers

I am trying to get this computer to work and every time I fix something another issue shows up. It is like a sinking boat in a carton. First it was slow and just acting up. After a few tweaks I got RestoreHealth to run and fix the issue. No SFC isn't reporting
any errors. For the longest time chkdisk wouldn't run manually but every startup it would run says checking.. fixing... fixed. This would happen on every startup now that is solved and it reports back okay. There were some drivers not working got
those working. Visual Studio had some sensor drivers that were reporting errors to it is uninstalled to rule out that. Currently one USB port won't install any drivers for the device plugged in, or use a driver already installed. Other ports work and all the
devices plugged in work in other ports. I would assume the port is bad but there are some programs that used to work and now don't. I am thinking there is an issue installing programs but I am out of my depth currently.
One think I am wondering is about a line in the CBS.log. I really wish I could find a resource to learn more about how to read the logs. I know how to read some but there are things I just don't get, yet. A link to an article(s) about CBS logs
would be great.
Here is the line I am curious about, even if it isn't part of the current issue I would like to know for futurereference:
SQM: Failed to start upload with file pattern: C:\WINDOWS\servicing\sqm\*_std.sqm, flags: 0x2 [HRESULT = 0x80004005 - E_FAIL]

Buying External Drive that Only Needs One USB Port?

The optical drive on my 2007 MacBook Pro has been dead for about 6 months. I need to get an external one so I can install some software, but I am having trouble finding one that only uses one USB port, as there is only one on each side of my notebook. I went to Best Buy today, and the only one they had that is compatible with a Mac needs two side-by-side USB ports.
Does anyone know of any good Mac compatible external drives that only require one USB port? I am interested in purchasing one by LaCie, but their site does not specify how many USBs it requires.
Any advice you can give me will be greatly appreciated!

Welcome to Apple Discussions!
You might want to consider a FireWire powered optical drive:
http://eshop.macsales.com/shop/firewire/optical-drives/
A FireWire port will deliver more power, so you would only need to use one FW port. The people at OWC are very Mac knowledgeable and could help you to pick one out. Your 2007 MBP should have both FW400 and FW800, so you could use either port.
Good luck!

One USB Port not Working Properly on MacBook Pro 3,1

I have an older macbook 3,1 running Mavericks OS and recently one of my left USB ports has not been:
1) able to eject external hard drives plugged into it (I have to force eject)-instead it gives me a message that one or more programs may be using it (even though I don't have any programs using it). The hard drive is being powered by USB has a 3.0 connection although this wasn't a problem in the past... I tried the other USB port and it can eject just fine from that port.
2)Intermittent communication with mouse.
Not sure if this is a hardware issue but when I try to run diagnostics on this laptop by holding down the "D" key at startup it doesn't take me to diagnostics. I no longer have the discs for this laptop (containing said hardware test) so I can't boot the diagnostics from that discs. In lieu of a hardware test I opened CONSOLE and did a search for USB and there were a couple of these messages:
8/29/14 12:13:43.000 AM kernel[0]: **** [IOBluetoothHostControllerUSBTransport][SuspendDevice] -- Suspend -- suspendDeviceCallResult = 0x0000 (kIOReturnSuccess) -- 0xdc00 ****
Is this a logic board issue? Would rolling my OS back to pre-Mavericks work? The problem didn't emerge right when I updated to Mavericks however I have had luck changing OS stuff (updating or rolling back) with faulty USBs...
Here are other troubleshooting methods I have attempted with no success:
-Disk Utlity (repair disk and permissions)
-RESET PRAM NVRAM
-Remove battery
-RESET SMC
-Shut Down
-Run Disk Utility @ startup
I'd love to get access to a Hardware Test compatible with my macbook. The links I have found online are to incomplete files. If someone @ Apple could send some Hardware diagnostics tool my way via a disk image that would be perfect.

Did you boot into Recovery or try & run OS X Utilities, to attempt a test?
Depending on the computer, that may be your best bet, short of taking
the computer to an Apple Store with Genius bar; or to an AASP who is
trained in Apple repair & testing services.
A replacement of original install restore DVD with the correct AHT on
a bootable DVD, could be obtained by contacting Apple support or
the main online Apple sales, or applecare; there would be a fee.
They'd need to know the Serial Number and product info, and you'd
have to provide a form of payment in order to get replacement discs;
and if the computer is way too old, those may be harder to get now.
The main system tools could be installed in Recovery partition.
And Ms Sammit may have answered this.
Good luck & happy computing!

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.

Late 2011 MacBook Pro; one USB port not recognising anything

Hi,
I've had my MacBook Pro since January 2012, so I believe it is the late 2011 13" model. I'm currently running OSX 10.9 although the problem I've been having has been going on around 3 or 4 months, I think I had OSX 10.7 installed when the problem started.
One of the USB ports on my Mac (the one on the left when looking at them face on) is not recognising my external hard drives, or recognising/charging my iPhone when plugged into the USB. The other USB slot works fine and recognises external hard drives, however when I insert the hard drive into the faulty USB input, although the hard drive lights up and starts whirring as if it is ready to start functioning, it does not appear under the 'Devices' tab of the Finder screen, but does appear and function when using the other port.
Similarly, when I plug my iPhone 5 into the faulty port it is not recognised/does not start charging, however if I leave it running and come back later I often have at least a level of increased battery life which suggests that it does intermittently charge from time to time, and again it functions normally when using the fully functional port.
I've tried the NVRAM reset as I have read in another post but to no avail. Is this likely to be a mechanical fault over a software problem, and if so what could be wrong with it?
Thanks for the help in advance.

thank you shootist, at least now I know the problem is as serious as I dreaded, but will not loose hope waiting for a miracle and the port works again

One USB port does not work with external Disk or USB key

Hello,
Back to my iMAC there is 3 USB port. The second one - in the middle - does not work pluging an external Disk, an USB key or an iPOD nano. However it works well connecting a Wacom tablet.
Is there an explanation to this behaviour ?
More the keyboard is plugded on USB port 1 and the mouse on the keyboard. Time to time - especially at reboot - I have to unplugged the mouse and plugged again it in order it works.
In advance thank you for your answers
Regards

Since it does not work for three different devices, I will assume it is not something simple like a faulty USB cable. Since it does work for one device, I will also assume that the port is (at least partially) working.
As a test to narrow down the cause, I would try restarting from your Mac OS X installation disc (insert disc and restart with the C key held down).
At the first Installer screen (after language selection), go up the menu bar. Under Utilities, select to run Disk Utility. Now, connect the USB drive into that center port. Does it appear in the Disk Utility sidebar?
Please post back the result...

One usb port does not work

one of my usb ports is fine the other will charge but not transfer any data.

Thank you for your prompt reply. My Macbook is, unfortunately, older than one year and I have not AppleCare. I have been into the Apple store, they suggest me to buy an other laptop. Probably because the repair is more expensive than a new Macbook.
Anyway I have not intention to chane the computer because is less than 3 yrs old, and it wors very well except usb.
thank you again
