My USB ports won't recognize any devices. Thoughts?

I am still using Mountain Lion, and I have been warned about updating. My USB ports will not recognize or connect to any external devices. Any thoughts?

Try resetting the SMC. Use the procedure for "a battery you should not remove yourself".

I'd start by looking in system profiler.
the blue Apple icon > About this Mac > More info...
goto the hardware section. Scroll down and click on USB
See what happens when you have the device plugged in & not plugged in.
Move keyboard & mouse around to verify that ports work. Plug device in a port that worked with keyboar or mouse. Keyboard usb ports are rather low power.
Perhaps device is taking too much power. Are devices power or unpowered? Try connecting devices to a usb hub.

Macbook Pro 15" USB PORT DOESN'T RECOGNIZE ANY DEVICE.

I got my macbook pro 15" for about 1 year and 2 weeks ago, when I turned on my macbook and put my mouse ( Death Adder) into the USB PORT, my macbook DOESN'T RECOGNIZE IT. There are 2 usb ports on my macbook, I tried both port and there was only one port work correctly, the other one didn't work at all, I also tried to put my memory stick, external hard drive, vodafone 3g usb, ipod,....into that USB PORT but non of them worked. Is there any one here have the same problem???? Can you guy help me please. I stay quite far away from Apple Store so it is hard to bring it to repair. I tried to reset SMC, Update Software,...but still not work...HELP ME PLEASE...

I can't fault your troubleshooting. Sounds like a bad port.
Home remedies are limited. You can grab a magnifier and shine a flashlight in there. If you see any foreign material, use a toothpick or other non-conductive tool to extract it. If you can, give it a good blast of (dry, canned) compressed air to blow any particles loose.
Sometimes you can trick a flaky USB port into working at least intermittently by plugging in an extension cable or right-angle connector. Play with a device that lights up so it's easy to see whether it's working.
Take a hard look inside the connectors at the end of your Death Adder and other frequently-used devices. If you see any corrosion or bent pins, that's what damaged your USB port.
If the port requires physical repair, it's best to use Apple or an authorized dealer because if they make things worse while trying to fix it, they have to make it right. Joe's Appliance isn't similarly accountable.
If you need more USB ports, ExpressCard to USB adapters are dirt cheap.
Good luck.

Restoring Your Nano When The USB Port No Longer Recognizes The Device

I can't say for certain if its coincidental or not but as soon as the latest update of v9 for iTunes came out, my computer stopped recognizing my iPod (1st Gen Nano) through all the USB ports.
First, I tried the Nano on a different computer with Windows Vista but the the latest version of iTunes had also been updated on that machine. The laptop also would not recognize the device through any of the USB ports.
Second, I switched cables. Same problem.
Third, I reset the device. Same problem.
Fourth, I tried to update the drivers on the device manager. Same problem.
Fifth, I uninstalled iTunes per Apple's uninstall instructions and that was to no effect.
Now my last option is to restore the device, however because I can't get it to be recongized on any computer I own- I don't know how to do this? Do I take it to an Apple store? Is there a manual way to restore the device to factory settings since every computer I have access to won't recognize the device?
Thanks!

I have exactly the same problem. After updated to the latest version of iTunes 10, my 5th gen ipod stopped being recognized by my Windows 7 Computer.
I've tried:
1. Un/reinstalling Itunes 10, then updating to 10.1 or whatever was the latest one as of 9/30/10.
2. Using a different iPod USB cable to connect to the computer.
3. Using a different USB port.
4. Trying the iPod on multiple computers.
5. Manually selecting the driver within Device Mananger in Windows 7 from "Unknown USB Device" to "Apple USB iPod Driver".
6. Restarting my computer, multiple times.
7. Resetting my ipod "Menu+Select buttons for 6-10 seconds"
From what I understand I could resolve this problem by restoring the iPod to its factory settings, but since I can't get it to be recognized in a computer I am stumped.
This will be my third iPod in 4 years that has crapped out (out of warranty of course) If I can't get this fixed I'm buying a Zune.

ITunes 12 for iMac won't recognize any devices

Just upgraded to iTunes 12. Now none of my device (iPhone 6, iPhone 5, iPad, iPod) are recognized. All. Connections are good, never had an issue before. Tried uninstallIngrid but iMac won't let me delete iTunes to reinstall. All settings are good and have tried powering off and on.

Hello Anlumsdaine,
Thanks for using Apple Support Communities.l
In iTunes 12, the location to where you would see your iOS devices connected has changed. Take a look at the picture below on where you can locate your devices. If you still do not see your devices when connected, follow the article linked to at the bottom of this message.
Sync your iPhone, iPad and iPod with iTunes using USB

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:

USB ports won't work

Hi, I recently bought a Probook 4441s-445TX. I installed Windows 7 Professional 64 bit on it but I couldn't get my 2 USB ports on the right side of my laptop to work. I looked into this and it seems like HP Probooks series have similar issue as well. The USB ports on the right (USB 2.0) don't work at all, they won't recognize any devices nor they can recharge any devices via USB cable.
Any suggestion? Am I missing a driver here (I checked Device Manager and it says I miss one driver but it's unknown device with Hardware ID "ACPI/HPQ6000" which I still couldn't find the driver for it, btw, but I don't think it has anything to do with the USB ports.

Hi:
If the notebook is still under warranty, it is time for you to call HP technical support.
Good luck,
Paul

MacBook no longer recognizes any devices that require the USB port (mouse, iPod, etc.)

After doing my latest software update, my MacBook no longer recognizes any devices that require the USB port (mouse, iPod, etc.). I've restarted the computer and that didn't help. Any thoughts on what to try? (I've already restarted the computer.)

Try using the procedures in this article to eject the disk.
Best of luck.

When I plug in my IPOD Nano into a USB port, the computer recognizes it as a printer. It then attempts to install the printer software, which is already installed. The only way to fix it is to unplug the printer. Any thoughts?

Turn the printer off.

My usb slot won't recognize a usb device

I have 2 usb slots.
Plugged in a flash drive and only 1 of the slots recognizes the flash drive. I don't see the flash drive either on my desktop or in Finder when plugged in to the 2nd of the two slots.
I've done all recent updates.
Have OSX 10.8.5
I tested 3 sandisk flash drives. The slot closer to the monitor won't recognize any of the drives.
I logged out and logged in as another user and again, slot closest to monitor won't recognize any of the flash drives.
I also tested the 3 flash drives on another macbook I have and both slots recognized the flash drives.
Any rec's or ideas to help?
Thanks

I plugged in my iPhone5 and nothing, no connection on this one usb slot. Connecting via the other slot a-okay though.
Unfortunately my applecare plan expired a week ago! Hah, how's that for timing!
I have appt to go in to store.
Thanks

Laptop won't recognize any ipods

OK, so I have an ipod video, a click-wheel ipod and a new shuffle, and my gateway laptop won't recognize any of them. It recognized them all until earlier this week, and the USB ports still work with my flash drive and mouse. I plugged the ipods into another computer using the same chord and they work fine. I got the ipod video replaced at an apple store, and still nothing. I plug the ipod (any of them) in and in the device manager it shows up as an unknown device. I tried reinstalling the driver, but I get nothing. I've restarted the computer of course, and have restarted the ipods (except the shuffle). I've gone through the troubleshooting on the apple support page, and am at my wits end. any suggestions?

I went through the troubleshooting page and went BACK to a genius bar and got the ipod video replaced again (they said it had a bad hard drive). I still have the same problem though. I think my computer's hard drive is going bad, but I'm not sure. The ipod is reading, but I can't copy any music over to it now ("the disc can't be copied to or read from"). Also, when I connect it to my older PC, I fill it up with music, disconnect the iPod and see that it's blank! I look in the "about" section of the ipod's settings and it shows that memory is being taken by music, and when I plug it into iTunes it shows the music being there.

See the chart below to determine whether you can upgrade your device and what you can upgrade to. If you do not have a Software Update option present on your iDevice, then you are trying to upgrade to iOS 5 or higher. You will have to connect your device to your computer and open iTunes in order to upgrade.

Iphone was in the middle of an update, and an error occurred. I think it is stuck in "restore" mode, but my computer won't recognize the device. How do I get it to work?

My iPhone 4S was in the middle of the latest software update while connected to iTunes on my PC. After it took 45 minutes to download, a pop-up came up and said that an error had occured and it couldn't be updated. I made a mistake and clicked "Okay" instead of "More Information", and now my PC won't recognize the device and connect it back to iTunes. This happened to me last time I updated it, but I've tried everything I did last time and it won't work. I have a feeling I didn't have enough storage on my phone to update it, but now I am stuck and don't know what to do. My phone is frozen with the iTunes logo and the USB drive and says to connect to iTunes. What can I do to fix it?

If this has happened more than once the problem is likely on your PC.

Printer connected to Airport Express USB port won't come online after firmware 7.6 upgrade. I've tried backing up to 7.5.2, but it still shows offline. It is a Canon iP4600 printer and I'm running OS 10.6.8. I've powered everything down and still no go.

Printer connected to Airport Express USB port won't come online after firmware 7.6 upgrade. I've tried backing up to 7.5.2, but it still shows offline. It is a Canon iP4600 printer and I'm running OS 10.6.8. I've powered everything down and still no go. I've connected the printer directly to my MacBook's USB port and it works fine. Any suggestions?

I have an iP4500, which I assume is quite similar to your model.
I had to reset the printing system to get things printing again. Only takes a few minutes and no problems at all since I did it a week ago or so.
Plug the printer into the USB port on the Express and restart the printer.
Open System Preferences (gear icon on the dock) and then open Print and Fax
Right-Click in the printer area on the left and select Reset Printing System
Then click the + (plus) button at the bottom of the printer list to install the printer again.

IMac won't recognize midi device

IMac won't recognize midi device (Roland Fantom) which is connected via USB only; no midi interface. I have rebooted both the Roland and the iMac, still no go. I have manually added the midi device under Audio Midi setup, still none of my apps will recognize the device; Logic Pro, ProTools and Sibelius. How do I get this configured? I've read through some other posts and nothing has worked.

Its standard for all computers - if you have 3rd party things that do not work - contact that company - they may have a driver for you to download specific for mac.
Some 3rd party things are windows only - probably same for Mac.

My USB ports won't recognize any devices. Thoughts?
