All USB stops working after restarting iMac, please help!

I am having a serious problem with my iMac and i'm at a loss of what to do. I have a 24" imac with 10.5.6 and about a week or two ago I restarted my computer only to find that none of my USB ports were working. I thought it was a fluke so i just restarted again, only to find out that they still wernt working. I was forced to do a restore because I couldn't find a fix so I booted up from my leopard disc and did a restore from my time machine backup. I thought all was well and good until i restarted again yesterday. The same exact thing happened so I did another restore. Well, I just needed to restart my computer again and what do you know, my USB stopped working again! I have repaired permissions, done the apple hardware test, reset the PRAM, and verified the disc to see if there was anything wrong with it. I am at a total loss on what to do and Im really not looking forward to doing another restore only to have it do the exact same thing. Please help!

If you haven't tried this, try resetting the SMC: http://support.apple.com/kb/HT1543?viewlocale=en_US
When you booted from the restore disk, did you run Disk Utility to check the hard disk for errors?
If not... make sure and disconnect anything connected to the USB ports first,
To check the hard disk:
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the Menu Bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click the Verify button. If DU reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.
Also, click the Apple logo top left in your Desktop, click: About This Mac, then click: More Info
That will launch your System Profiler. Under Contents on the left, click: USB and make sure your USB information is there.

Cinema display USB stops working after upgrading to mountain lion

I am using a newly bought 27' Cinema display + mid 2011 MBA. an Apple USB keyboard is attached to the display USB port, and a logitech mouse is attached to the USB port on the keyboard.
After upgrading to mountain lion, when I unplug the thunderbolt from MBA, and then plug it back, the USB keyboard and mouse stops working. Moreover, I cannot open anything in System preference, and cannot properly shutdown the machine!
Please help on this issue.

Launch Terminal, type or copy/paste the following:
killall Dock
Hit enter.

[SOLVED] USB stop work after suspend (only right ports!!!)

Hi,
It drives me crazy!
I recently installed Arch on my new laptop SAMSUNG NP900X4C that have 3 USB ports, one in the left side and two in the right side . When I boot the system (or reboot) all USB ports works fine, but after system suspend like close lid, only the left port go back work. dmesg shows nothing when I plug a pendrive in the any right USB ports, even less lsblk.
This is my dmesg out when I connect the pendrive in all ports after boot:

Nothing appears about the USB ports 2-2 and 2-1. Any ideia?!
I even tried to install laptop-mode-tools and set CONTROL_USB_AUTOSUSPEND=0 but didn't work

Oh crap! I am kid with his new toy...
After a lot of google it I read something about firmware control the wake up of USB 3.0 and when I entered in this laptop BIOS what I found?! This option disabled:
USB S3 Wake-up [Disable]
So, just enable it and all my USB ports go back to work after suspend. I don't understand the purpose of it disabled by default.
Anyway I am sorry for this newbie mistake.

USB stops working after BIOS flash to ABCN74WW on new Z70-80

Hi,
I started with Windows 7 installation on my brand new Z70-80 which worked fine, USB 2.0 ports had been working.
After flash of BIOS to ABCN74WW USB ports are not working any longer. I already tried soft BIOS reset by unplugging power and battery and pressing the power button for 20 seconds. USB ports are still unaccessible after this, a USB stick flashes for a moment, mouse LED is on, but no laser and no operation at all. Same when I start brand new windows installation.
Are there known issues with this BIOS version ? Can I undo the BIOS flash ?
Kind Regards
Solved!

First USB port stops working after random time and won't work until I restart

Hey guys
I have this problem on my late 2011 Macbook Pro 13 inch,
It's been for a year already and it really freaks me out and drive me crazy
My first USB port next to the thunderbolt stops working after like 3 days, and it won't respond until I restart my computer or log off and log in again.
If I restart my computer, USB stops working after 3 days and won't respond until I restart
If I log off it works for like a couple of hours and then stops again
I have tried EVERYTHING, SMC reset - no luck, PRAM reset - same results, Upgraded to lion same results, Upgraded to mountain lion - SAME RESULT
And I can't take it to an apple store because I'm not from the US
I am 100% sure this is a software problem and I've seen here that many people have faced this problem
Please help, it really freaks me out

I'm sure this isn't what you want to hear but unless you really are using your laptop 24 hours a day, is there any reason why you don't just shut it down and reboot when you're ready to use it again? I have to wonder how many other MacBook Pro owners potentially have the same problem but when they quit computing for the day, their computers quit too.

Right USB Port stops working after disconnecting device since 10.9.2

Hi,
Since updating to 10.9.2 the right USB port on my MBA stops working after diconnecting a device (tested: external hard drive, USB flash drive, USB HSPA Modem). The only way to get the port recognizing the device on that port is to do a restart. If the device is connected from starting the MBA it works fine, if I then eject the drive and reinsert it or a different USB device the device doesn't get recognized. The devices do get power, my WD passport ultra spins up just fine, the USB HSPA modem also indicates it's working (with signal) but nothing shows up in finder or diskutility. If the modem is connected from start (and thus working) and then disconnect from the internet but not remove the drive I can reconnect to the internet. The problem only occurs after disconnecting the device. The port becomes inactive. The left USB port works as expected.
Steps I've taken:
Disk Persmission
PRAM
SMC
Reapplied the 10.9.2 update
Sent feedback to Apple

Nothing out of the ordinairy. Thanks for any help

It's an Apple Pro keyboard and mouse, the dongle is
plugged into the Mac and not the keyboard. The same
set-up is, and has been working on all our other
Macs.
The sleep issue sounds interesting- hum, maybe...
Is your keyboard plugged into one of the USB connections on an Apple monitor? If so, you may want to change that connection to one that is on the G5 itself. My monitor came with a warning note indicating that problems will likely occur if the keyboard is connected to the monitor.
I also had a problem with the automatic sleep function. After much trouble-shooting and a logic board replacement, it was concluded that coming out of the automatic sleep function with any USB device active would freeze the entire USB bus. After disabling automatic sleep in system preferences, I've had no freezing problems. My machine works fine with the manual sleep function in the Apple Menu.

I have pluged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?

I have plugged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?
if the device I connected have caused this, shouldn't the macbook itself have some type of protection that should prevent this from happening.
because when I took it to an apple certified maintenance shop, the guy said that now it could only run while connected to the power. it won't run on batteries. and that I have to change the motherboard.
can I just replace the damaged part only, would apple consider this as a design issue and they could pay for it, or should I just buy a new motherboard for 800$.
Help.

BB1B2,
The problem is in finding a tech shop that will/can do board level repairs on Macs. They are few. And I certainly wouldn't spend $800 on a new logic board - I would replace the computer if I had to pay that much!
You could call around to a few repair shops and see if they feel competent to isolate the problem and do a board level repair - but I'm afraid, in the end, that your search will be futile.
Sorry,
Clinton

USB hub and internet sharing stop working after sleep

Hi,
I have a relatively new Bluestork USB hub I purchased to connect multiple USB devices I have at the same time. It used to work correctly under Leopard, but now it stops working each time the computer wakes up from sleep. I have to restart the computer for it to start working again. Both link and power LEDs stay on, even when the hub is not recognized.
My second problem is related to internet sharing. It stops working after each sleep/wakeup cycle and the only way to make it work again is to restart the computer. It used to work correctly before Snow Leopard as well.
I have all the Mac updates installed.

Thanks Barry.
The hub is on its way to the manufacturer for after sales service...
But the issue with AirPort remains the same, even after resetting SMC.
Some clarification:
* It happens just after computer wakes up from sleep. Restarting solves the problem and the issue doesn't arise until computer goes standby again.
* The whole WiFi card becomes unresponsive. It is not only the Turn Off button, but the whole functionality is stopped. The card can not be activated/deactivated and it doesn't connect to any network. If it is used for internet sharing, clients are unable to connect.

Hi, i have an IPod Touch 4g. One of the earphones just stops working after while,no matter how many times i replace them. What do i do?

Hi, i bought my IPod 4G about 7 months ago. After about a mont of buying them, one the earphones just stopped working which became extremely annoying..so i bought a new set of earphones and they worked well for about 5/6 months and then one of them stopped working as well. About 2 weeks ago, i bought a new set of earphones and now the right earphone of that has stopped working as well. The thing is, the earphone doesnt just stop working on my IPod, it also stops working on my laptop...and now i am very confused as to where the problem lies. I can't keep buying headphones every other week cos that is just too expensive and i dont know if the problem lies with my IPod or what! The same thing is happening to my sister's IPod as they were purchased at the same time. What do we do??

This previous discussion discusses the same if not similar problem.

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem, make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

Help, 10.6.8 update, all usb ports stop working after 10hrs

I've been running 10.5.8 for ever and finnaly tried to update to 10.6.8.. After I did it, the usb ports all kick out any connected devises after around 10 or so hours. I ran of the install disk, using disc utillty, disk repair, and repair permisions a few times and it did not help.
I did the install a few times again to try to see if it would help and didnt.
i tried an erase and install and migrated everything over from my orignal back up external drive that is running 10.5.8 and issue is still there.
My old 10.5.8 back up external drive works fine and does not have this issue, and I have been using that as my start up drive instead and working from there. But that is not really a solution and a temp work around.
Any suggestions would really help. thanks!

I have a early 2008 macbookpro 2.8 duel with silver keys.
I purchaed the 10.6 disk from the apple store. I've had the machine for years and purchased it refurbished from apple.
I did the erase and install and migrated everything over from external drive, then did update to 10.6.8 and the usb ports still would stop working after a few hours.. Then I read on another apple community forus to reset pram, and pull out the power cable, take out the battery and hold power key for 5 seconds, then restart. that seemed to fix usb issue so far..
But overall my computer seems to be running slower then when using just 10.5.8 and it did not wake from sleep once and I had to force power off and restart.. But maybe its just getting used to 10.6.8. we will see..
Also, on another note, my battery is totally dead, and I can only run computer with power cable.. Will this affect things? it never did with 10.5.8..
Oh, on my erase and install, I just did the simplest version and did not do the full erase to zero using he advanced security measures.. I just did the one where it writes on top of everything..

USB audio DAC stops working after suspend

I didn't update my mediacenter running arch for a few months so I figured i'd reinstall it because of the filesystem, /lib and grub changes. Now after reinstalling I'm running into the issue that my USB audio DAC stops working after a suspend.
After a suspend speaker-test gives me the following error:
[user@mediacenter ~]$ speaker-test -c 2
speaker-test 1.0.25
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
ALSA lib pcm_dmix.c:1068:(snd_pcm_dmix_open) unable to open slave
Playback open error: -77,File descriptor in bad state
I've tried replugging my DAC and restarting ALSA, without any success. I have to reboot to get sound again.

Unless you can find a way to stop XBMC from using your DAC, I would try hunting down the update which broke it and file a bug report with the appropriate project. https://wiki.archlinux.org/index.php/Do … g_Packages.
I suspect it would be the kernel.
Yes I am suspecting the kernel as well. I'll try to change some options in XBMC to maybe get this working, and if not I'll see how far I can downgrade with the kernel. My last installation was a few months old so I hope it broke not that long ago.
Thanks for the help

Why does my iPod Shuffle stop working after a few songs?

I had my iPod Shuffle for about a month now and it's already causing me trouble.
I would play a couple of songs, but when I go to change it, it stops working. I turn it off and on again only to have it take me back to where I started off at (e.g. Let's say I have 100 songs, I start at 50 and I get to 55 before it shuts off. When I turn it back on, it starts at 50 all over again). This process would happen over and over again with seemingly no end.
So my question is, why does my iPod Shuffle stop working after a few songs and how can I fix it?
I already tried using the iTunes troubleshooting guide, but nothing worked.
Details -
4th Generation
I only use it at the gym or when I'm running
I've only used the Apple products that came with it so far
(e.g. charger, headphones, etc.)
881 MB are still left
Music stops randomly, no common number or pattern

I had the same problem, I purchased a new ipod shuffle, followed the instructions but it would stop after a few songs and I would have to shut it off, wait and turn it back on and it would go back to the same song and then once again, after a few songs it would shut off. I returned the ipod and got another one, same thing happened. This is how I resolved the issue.
1. open itunes, make sure its up to date, then connect your shuffle to your pc
2.on the left of the itunes window, select your ipod, then at the top select music then check the sync box and select "selected playlists"
3.then go back and click on your ipod on the left, a message will appear just select apply
all of your music should be emptied from your ipod.
4.delete all of your playlists on the left, this will not delete anything from your library. Delete the "purchased" playlist under itunes store on the left as well, once again this will not delete anything from your library
5.There should be an arrow just in front of your ipod, click on this arrow and you should see your music file for the ipod appear, this should be the only file that you see, everything else should be deleted.
6. go to your music library and check only the songs that you want to load into your ipod. Double click on each song to make sure that they all play.
If you find a song that does not play you should be asked to authorize it, don't waste your time that did not solve the issue for me, instead cancel to authorize the song and then delete the song and move it to recycle bin. Once the song is deleted a cloud should appear, click on the cloud and download the song again, when done, make sure the song plays and that it is checked.
7.After you have made sure that all of the songs play and are checked, click on your ipod once more, located to the left, check the box "sync only checked songs" then from the top select music. In the music window select "sync music' and then select "entire music Library"
8. Go back to the left and click on the arrow in front of your ipod, you should see the music file, click on the music file and you should see all of your music being loaded to your ipod.
9. When all of the music is done loading, eject your ipod by clicking on the arrow located after the battery symbol where your ipod appears on the left
10. Turn on your ipod and scroll through your songs to make sure that the problem is resolved.
Not sure if all of this was necessary but it worked for me.

USB stopped working after reconnecting iPod
