Macbook Pro USB port is not working

I have a Macbook Pro 15-inch mid 2010 running Mavericks 10.9.1, the problem is that one of de two USB ports stop working, does not recognize any USB divice. I already tried restarting the PRAM and the PMU and the problem persists. Please help!

Did you try a SMC reset? If you di and it still doesn't work thenn it is broken. The only way to fix it is to have the logic board changed.

1 of my USB ports is not working. Help?

Suddenly one of my USB ports is not working. No matter what I plug into it, it doesn't work. Any help or ideas would be appreciated. Thanks.

Not in the one that's ailing, but it does in the other one. I've also plugged in an external USB hard drive and that doesn't connect. Also a mouse's USB dongle and that doesn't work in the ailing one, but is fine in the other one.
I've also tried ( a couple of times ) to simple reboot hoping that would jog it, but that doesn't seem to help either.

Both my usb ports aren't working, Please help!

I bought a 500gb external hard drive that is usb powered. it was working fine a week ago but now i get a message saying a device draws to much power, therefore all my usb ports aren't working for anything any more. Not even a simple wireless mouse. I am using a macbook pro late 2011. also.....when i use the usb port closest to the charging port, the lights on he external hard drive turn on (yet i still get the message). When i use the other usb port, no lights turn on at all. does this mean one of them is just ruined completley??.
Thanks,

It actually did. After I uninstalled java and restarted my computer for the fifth time, the usb ports actually responded! I re installed java and the problem was fixed.

MacBook Pro USB ports only sorta working...

Both USB ports on my MacBook Pro have stopped being recognized. I can still synchronize my iPhone, but cannot use thumb drives or external hard drives. I've tried all the previously suggested remedies to no avail. Other thoughts, please.

Hey deanfromjensen beach,
Thank you for visiting Apple Support Communities.
That is odd that your USB ports are working to sync your iPhone but not working with thumb drives or hard drives. Do USB keyboards or mice work?
There is an article for help troubleshooting USB in Yosemite.

Port Forwarding not working (PLEASE HELP!)

I have been trying to port forward a Minecraft server for fun, however the port will not open no matter how many times I try. Here's what I've been doing: Enter 192.168.1.1 in browser and log in. Once on the home screen -> advanced -> port forwarding rules -> add port -> tcp -> any source -> single destination: 25565 (default port for a Minecraft server) -> add port -> udp -> any source -> single destination: 25565 -> apply -> fire wall settings -> typical security -> port forwarding -> select my computer I am on -> select the port forward I had previously created -> add -> resolve now & apply. The status shows as active, but when I use a site like checkmyports.net, it states that the port is closed.Is anyone else having port forwarding issues? What's the problem? Did I miss something? Thanks in advance.

Thanks in advance.Do you have an application on the internal device that is listening on port 25565? Port will only report as open if there is a listening appliaction on the port on the destination device. Try something simple that we know works e.g. remote desktop which uses port 3389Enable remote desktop on your computer - typically right mouse click my computer, select properties, select remote settings, select remote, select Allow connections any version.now logon to router select firewall settingsselect port forwardingspecify ip address of your machineselect Remote Desktop from services - will show tcp any -> 3389 udp any -> 3389select addselect apply Now try checkmyport.net and test port 3389If it doesn't show as open then it sounds like a firewall issue In either case you'll probably want to go back in and turn off remote desktop access unless you really want to access your machine from the outside. let us know the results.

My MacBook Pro's sound is not working! HELP!

This problem heppened when I was using my headphones.
When I try to change the volume on my computer, it gives me a sign that it is locked.
I have tried restarting, plugging and unplugging headphones, and fiddling in the port with a tooth pick.
Thank you

Do the internal speakers work?
Go step by step by step and test.
1. System Preference > Sound > Output > Internal Speakers
    Highlight Internal Speakers / Headphones
    Make sure that Mute is not enabled.
2. Hold the option key down, click the sound icon in the menu bar and select internal speakers or headphone.
3. Any red light visible in the headphone port
    Even if there is no red light visible, plug in the headphone in and out 6. or 7 times.
4. Launch iTunes and play a song. Try to move the volume slider in the mini player.
5. Close all windows and quit all applications.
     Launch Finder. Select Macintosh HD in the Finder sidebar.
     Macintosh HD > Library > Preferences
     Open "Audio" folder.
     Right click these two files and select "Move to Trash".
     com.apple.audio.DevicesSettings.plist
     com.apple.audio.SystemSettings.plist
     Close the window. Restart the computer.
6. Reinstall OS X 10.9 Mavericks

If this does not help, you may have to take the computer to the Apple store to have it checked out.
Best.

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

Invoke your warranty and take it back.

One of my USB ports is not working

Hello,
I just found out that one of my USB ports on my MacBook Pro (Early 2011) is not working. I usually use only one USB port to connect my external hard drive but when I wanted to connect my mobile phone and external hard drive at the same time, I noticed that my phone was not detected but it was charging. To confirm that there was someting wrong, I swapped the mobile phone with my external hard drive and what I found out was the indicator light on my external hard drive lights up but it was not detected by the MacBook. The other port works just fine.
Does anybody know what is wrong with the USB port and what should I do?
p/s: I bought my MBP in Malaysia early September and now I am studying in India.

After I went through the Apple Support Community, I tried the easiest and simplest suggestion first: restart my MacBook. Well I did it and the USB port seems to be working again and it reads my pendrive. Hope it will stay that way and never go wrong again. I really don't like going to Apple store because none is nearby.
Thanks for the reply by the way.

Audio output and left USB port is not working!

Hi! I have MacBook Air 13" late 2010, Audio output and left USB port is not working!
What happened?
Part No.: Z0JH000TE RS

If the left USB port doesnt work with an external mouse its seems to be a hardware malfunction of this USB port.
The newest BIOS is already installed?
Have you removed all USB ports from device manager and restarted your notebook?
If you have already tried this, contact an authorized service provider. The guys can try to fix this issue and it should be covered by warranty, if you still have warranty on this notebook. :)

My MacBook Pro internal speakers are not working, what happened?

My MacBook Pro internal speakers are not working, what happened? If I plug in earbuds or external speakers, there is sound. In sound preferences, internal speakers are not a choice. Why doesn't my internal speakers work?

Hopefully one of these steps should solve the problem.
1. Remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
2. Reset PRAM. http://support.apple.com/kb/PH4405
3. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
4. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.
Best.

USB ports does not work

Hi I have problems with not working USB ports. It used to work. I downloaded actual drivers at msi.com for my gaming notebook GX 60 Destroyer and now my USB ports does not work. What should I do?

What driver have you updated?
Try to do an EC firmware reset by removing the battery and the AC adapter then put the battery back with AC adapter attached.
Same questions like Pegasus asked, does all ports not working? which one exactly? What OS are you using?
Have you done any changes to the system? (for example: self-install OS or changing OS)

I installed windows 7 on my macbook pro. all is working but lan adaptor and sound od laptop is not working. please help me or send the link where i can download the these drivers.

If you are running Lion or Mountain Lion, the drivers are downloaded from within Bootcamp Assistant. If you are running Snow Leopard the drivers are on your Snow Leopard install disk.
Read the Bootcamp Install Guide for your version of OSx. http://www.apple.com/support/bootcamp/
Bootcamp questions should be asked in the Bootcamp forum where the Bootcamp gurus hang out https://discussions.apple.com/community/windows_software/boot_camp

T420 USB Ports do not work after installing XP

Hello my office has been using Lenovo's for some time now but we recently purchased a T420 and installed Windows XP SP3 on it. The issue we are having is that the uSB ports do not work. I have tried every driver I can find but still no luck, can anyone help?

hey chris0277,
could you check in Device Manager and see if there is any ? or ! symbol on the USB area.
If there is, i do recommend uninstalling the drivers from it and then visit http://support.lenovo.com and update your unit
