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.

What I'm noticing is that after a suspend "Subdevices: 0/1" gets changed to "Subdevices: 1/1".
Any help is much appreciated!

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

[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
Last edited by otto_simpson (2013-01-23 01:28:49)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 audio suddenly stops working
It's really weird. Regular audio output works fine, but if I plug in a USB audio device it will work for about a minute and then stop. I can reproduce this reliably with both a Griffin iMic and a C-Media USB audio widget. Once the device has stopped working, if I unplug it and plug it back in it wiil work for another minute or so and then stop again. This only started happening in the last week or so. Before that it was working fine for months. AFAIK I haven't changed anything. I haven't done any major software updates, and I'm not running any new applications.
Also, while it's not working, it's not off 100%. It seems to have something to do with the audio driver. If, for example, I do this at the terminal:
say hello world ; say hello world ; say hello world
I will hear "hello ... hello ... hello ..." (where the elipses indicate about a second of silence).
If I do:
say hello ; say hello ; say hello
then I just get little blips of sound.
Has anyone seen this problem before?Good Morning
Greetings from Babar Ali

USB Bluetooth adapter stops working after 10.8.5 upgrade
For several months I've been using an IOGear USB Bluetooth adapter and a USB KVM to share my Magic Trackpad between a Mac Mini and a MBP, both machines happily running 10.8.4.
Tonight I upgraded my MBP to 10.8.5 and now Bluetooth is apparently disabled when I have the USB adapter plugged in:
Now I'm left with the unappealing decision of using my Trackpad with only my Mac Mini, my MBP, or constantly repairing it with either to share.
I've been shockingly happy with this little trick, but I guess it was too good to last. Anyone have any ideas why using a USB Bluetooth adapter would stop working? Maybe I need a different adapter now?Thanks! That solved my problem. I just had to swap in my device id which was different than yours.
I converted my USB adapter's idProduct value from hexidecimal (0x2101) into decimal (8449) and added this configuration:
<key>BroadcomUSBBluetoothHCIController_Dongle - IOGear2</key>
<dict>
<key>CFBundleIdentifier</key>
<string>com.apple.iokit.BroadcomBluetoothHostControllerUSBTransport</string>
<key>IOClass</key>
<string>BroadcomBluetoothHostControllerUSBTransport</string>
<key>IOProviderClass</key>

Usb keyboard keys stop working after 10 minutes on mac mini osx lion
I am using a mid-2010 mac mini with opitical drive, updated to OS X Lion. Within the last two days I noticed a certain section of my wired keyboard eventually stops working. These are the right arrow key, as well as the 1, 2, 3, zero, period and enter keys. The virtual on-screen keyboard works just fine. I've come home from work and powered the mac and all keys work fine for ten minutes so it can't be that the keys are worn. I was going to take it to Apple Store genius bar but now I can't tell if it's the hardware or the lion software that's buggy.
I had terrible problems last year with the USB ports on my 20" display. They were made worse when I installed a USB 2.0 PCI card in my G5.
At the time the advice I got was that I should avoid using the display as a USB hub. Apparently the ports are only intended for devices relating to the display (whatever that means). Ridiculous if you ask me. I succesfully use my Cubase SX dongle in the back of the display but that's all. -

been updating drivers two weeks ago. bios mostly, the rest just refused to be installed, and after a while any software i been running , just shuts down the audio after 1-4 minutes. i am not sure if it has any connection but the usb , any of them, wont supply power to my cell phone and that happen along side to the audio issue.
I tried removing drivers and installing again but it didnt help. did the same with the software that related to the issue as well, but ... Nada !
Been investigating on google for hours and saw tons of this exact problem.
Any solutions?Did you ever try to reset the notebook back to factory settings using the Toshiba recovery disk?
If driver update or reinstallation did not help in the past and you have no idea how to fix the an particular problem, its advisable to run perform system recovery.
However, I think you should also try this workaround:
First of all uninstall the sound driver.
You can do that in device manager. Expand the area Audio, Video, Game Controller and uninstall /delete the sound driver (Conexant).
Delete also the High Definition Audio Controller entry (Intel and probably nVidia)
Then reboot the system.
After the reboot, the deleted / uninstalled devices should be recognized automatically by Windows system. After that you could test the sound again -
USB 3G modem stopped working after updates
Unfortunately I don't know which update broke it, probably the new kernel? But now I don't get /dev/ttyUSB* or /dev/gsmmodem devices. Here's a log, which looks different now, and I think maybe more similar to before I installed usb_modeswitch? I really don't remmeber, it's been more than a month and I don't have logs that old. Didn't find mentions "usb_modeswitch" in /var/log/ older than today.

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 helpIt'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 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,

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. -
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.. -
After i updated to mavericks, my usb ethernet adapter stopped working.
I'm not sure why, but when I updated my software to mavericks, my USB ethernet adapter stopped working.
I'm using that adapter:
http://www.edimax.com/en/support_detail.php?pd_id=445&pl1_id=5&pl2_id=26
After I updated to Mavericks, I installed the driver in this page, but it didn't work. Then I googled "AX88772" which is my adapter's part no. or something like that, and I installed that one:
http://www.asix.com.tw/download.php?sub=driverdetail&PItemID=97
I wasn't expecting that work but that did work. So, I think the solution of the problem is finding the right driver. I hope you solve your problem too. -
USB Ethernet stop working after hotplug
I have found that my Apple USB Ethernet dongle stop working if I plug in another USB device. This happens both using a USB hub, and when plugging directly into the MacBook Air. I also see this problem when using a similar dongle from another supplier (called AX88x72A). The USB Ethernet dongle works fine after booting, with status "Connected", but if I plug in another device like my phone or a USB drive, the status changes to "Cable Unplugged" after a few seconds, ifconfig no longer show the en1 interface, and syslog gives a few error lines such as:
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: en1
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: Ethernet \[AppleUSBEthernet\]: Link down on en1
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
Fri Jan 13 13:17:19 Airbook-II kernel[0] <Debug>: AppleUSBEthernet::prepareForFlash - Link down, Device 87bf600
After this, I must reboot the MacBook Air to get the dongle working again. Do anybody know how to force the AppleUSBEthernet driver to rescan the device tree (or something similar)?
With regards,
Birger Retterstøl OlaisenI have exactly the same problem here (MacBook Air 2,1 - OSX 10.6.8). After several tries (and reboots!), I've found that an unload/reload of the USB Ethernet driver works.
Note that operation is not automatic: I have to execute commands in a terminal in order to retrieve my Ethernet connection... but it is far better than a reboot!
So, if you want to test my method, once you have plugged a USB key (or after an hotplug of your USB-ethernet dongle), you can execute these commands on your terminal (note there are 2 lines and no space in the kext name, a space may be inserted by this forum):
sudo kextunload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
sudo kextload /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleUSBEth ernet.kext
Of course, i've made a small script with these commands, and copied it on my PATH so it is even easier to execute it. It works perfectly for me, and I hope it could help.

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 outElectroSpyzz wrote:

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.
