USB headset is no longer recognized after El Capitan updated 10.11.6

After the last update to El Capitan 10.11.6 my headset Plantronics USB C435-M has stopped working.

I tried:

(1) connect to other usb ports

(2) reset NVRAM

(3) reset SMC

4) sudo killall coreaudiod

create the new test user 5) and the connection

(6) Contact Plantronics support: they don't make drivers for this helmet and it uses the operating system built in drivers

They send back me to Apple

(7) tried on other machines apple also runs the last el Capitan: does not work

(8) tried on other machines in the window running windows 10 > recognizes

(9) tried to plug into non-plantronics headset (Jabra) to my macbook > works

It seems that the last update of El Capitan, some USB devices stopped working properly. Please release a patch.

Did you have a Plantronics support on any updated for your helmet C435-M drivers?

  • Tap to click and three fingers slide no longer work after El Capitan update - MACBOOK AIR early 2014

    Things no longer work after the update are:

    1. TAP to click (I checked it on SYS PREF > TRACKPAD > tap-to-click)

    2 finger three windows

    3 Thre finger of several files and text selection.

    I have selected three fingers slide accessibility and options of the trackpad iv done 4 fingers to mision statement and app expose, but the problem is that these feature mission statement and the rest three fingers still work. :@

    It was just beautiful in yosemite please give a solution.

    Please read this message before doing anything.

    This procedure is a test, not a solution. Don't be disappointed when you find that nothing has changed after you complete it.

    Step 1

    The goal of this step is to determine if the problem is localized to your user account.

    Select the feedback connections* and log in as a guest. Do not use the Safari connection only 'user comments' created by 'find my Mac '.

    While signed in as a guest, you will have access to your documents or settings. Applications will behave as if you use them for the first time. Do not be alarmed by this behavior; It's normal. If you need any password or other personal information in order to complete the test, save, print, or write them before you start.

    Test while signed in as a guest. You have to re-create your trackpad settings. Same problem?

    After testing, log on to the guest account and in your own account, disable it if you wish. The files that you created in the guest account will be automatically deleted when you log out of it.

    * Note: If you have enabled 'find my Mac' or FileVault, then you cannot activate the guest account. The login 'User comments' created by 'Find my Mac' is not the same. Create a new account to test and delete it, including his home folder, after testing.

    Step 2

    The goal of this step is to determine if the problem is caused by changes in the system of third party that load automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.

    Please take this step regardless of the results of step 1.

    Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

    Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

    The login screen is displayed even if you normally connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

    Test in safe mode. Same problem?

    After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of steps 1 and 2.

  • VMDK is no longer recognized after cold move

    As part of the migration of storage of a data to another store, I close the machine virtual and made a gesture of 3 files vmdk to a data to another store.

    After the move is completed, 2 3 come vmdk files fine with the virtual machine, but the 3rd vmdk and also the largest 200 GB now is no longer recognized as a hard file. I have attached a screenshot.

    Is anyway to fix what looks like a corrupted hard? Any suggestions would be welcome.

    Except for the last two lines with the ' ~ ' the vmdk file looks ok. Please remove the last two lines of the vmdk file, to make sure that this does not invalidate the file. If you are not familiar with vi (dd deletes a line), you can use nano (nano w HOTWVGEUAT01_2.vmdk)

    If this does not please compare the file vmdk with another of the differences (apart from size).

  • L875D-10th satellite no longer starts after the system update

    Hello

    After a Windows Update yesterday my system unbootable - little matter what I try!

    And I tried many things to get it started again.

    think like:

    -Passage uefi depents csm and back on trial
    -Different installation DVD original Windows (Win 7/8 x 64 & x 86)
    -Different USB key
    -Erase the HDD on an external PC
    -Reset the UEFI with F9 while inside - system breaks down right!
    -Remove the BIOS battery and battery hand while it is also removed from power like 2 hours
    -Replace the DVD with another
    -Tested external RAM and HDD - ok status

    I can access the menu of boot with UEFI himself (channels here is saved and system restarts), but past that I just get a black screen with backlit, on NumLock no longer, have powerdown to reset.
    At startup, I see the Toshiba Logo.

    Is there an external means to completely reset the UEFI next to Load Defaults while in there?

    Any other suggestions I can do?

    (Sorry for my bad English and greetings from the Germany)

    Hello

    > Is there an external way to completely reset the UEFI next to Load Defaults while in there?

    There is no other method to change the mode of the UEFI.
    You must do it in the BIOS (press F2)

    In order to boot from the external environment or to install systems as Windows 7 or other, need you to change disable secure startup and must pass the CSM UEFI.

    In which case you would use the Toshiba recovery media, these changes are not necessary.
    Have you tried to reinstall the system using the Toshiba Recovery Disk or Flash Recovery USB stick?
    Did you create this recovery media in the past?

  • My CD/DVD drive no longer works after installing an update for Roxio Burn, (it was working perfectly until after the update).

    Hi, my CD/DVD drive has stopped working after I installed an update for Roxio Burn. I tried uninstalling and reinstalling, updating all windows and my device driver programs, but I just comes up with one, "Windows cannot load the driver for this hardware device. The driver may be corrupted or missing. (Code 39) ', warning. The DVD/CD player that I use is called TSST corp DVD +-RW TS - H653G

    Hello

    Code 39 means that the driver is corrupted or missing.

    Having too many CD/DVD programs can cause strange problems, especially if they're loading of parts of them.
    Selves at the start because they will be competing for resources. This does not mean that this problem was caused by
    These however is a possibility depending on which and how many you have installed.

    Definitel check with the help of Roxio and their forums - you may need to uninstall Roxio to see if this
    allows the reader to work (not re - install until the issue is resolved).

    Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.

    Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
    ends. Remove and replace, do not just tight. For laptops, you can often clean power and
    contacts data with a pencil eraser.

    Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
    manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

    ===============================

    Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD

    Did you follow the Troubleshooting Guide for the reader who still does not work? There are

    Check with your Maker system and a device for the two possible firmware updates and the
    correct registry entries for your car.
