El Capitan USB question

Hello Apple,

Since the upgrade to 10.11 'el Capitan' several of my USB devices does not work properly, which up to now worked perfectly. To name only a few, these include the eBook reader Sony PRS - T3, AVR, ST-Link2 programmer, FT232 programmer (sometimes). In addition, VirtualBox and Parallels, which I use frequently, have questions calling for USB devices. Apparently I'm by far not the only one, as revealed by a quick search on the internet, for example

Common to all these pages share the conclusion that the issue was introduced by Apple with 10.11 and that until this Apple support could not answer - at least in a useful way. And the advice to wait for the driver updates is not always an option for me the two for reasons of time or because support for example, PRS - T3 has been abandoned altogether.

To sum up: there are a lot of people and equipment who have a problem of USB introduced El Capitan. The problem persists for some time now and there is no support by Apple, or at least a statement how they intend to solve. This is the shit!

I'm a Mac user since the days of--oh, I don't know even the name of the model! And above all, I was very satisfied. But I must say that lately I wonder if that faithfulness is well spent. For me (and others) crucial things that worked perfectly before now fail and apparently Apple cares.

Think again, Apple...

A dissatisfied customer

I have the same problem with USB: I have a cam action by Garmin, which had functioned normally before the El Capitan 10.11. No it was not acknowledged more. Using the DMESG command in the terminal, when the cam is connected to the USB port, I get this feedback:

002223.783219 HS01@14100000: AppleUSB20XHCIPort::resetAndCreateDevice: unable to create the device, disabling port

It really a mess and I don't understand WHY Apple has not solved this problem despite of El Capitan 10.11.03 was last updated. I really get off at Yosemite. But really I couldn't think that apple were so unprofessional!

  • Tektronix AFG 3253 USB question

    I'm having some problems with running a test of long duration (100 + hour) with a Tek AFG 3252.  I was using a converter USB / GPIB to communicate with him.  For some reason any USB port down and he refused to communicate after that and the settings are pasted on the AFG.  The issue seems to occur at random times and after a while.

    I checked the USB sleep on the port settings and it is not permissible to put he's asleep.  I also tried to use a hub USB powered and it does not solve the issue.

    I will try to convert the right USB communications today or tomorrow and see if that makes a difference.  If I can't make it work reliability with USB I'll try Ethernet.  We had a problem like this with a range of Tektronix finally had to convert the comms in Ethernet.

    Has anyone else had a problem like that?  If so what did you do to solve?

    Does anyone know if there is a sniffer software and/or hardware that can be used for USB ports?  I would like to know if there are any detectable reason this port is stalled.

    The problems get fixed if the USB cable is unplugged and plugged in the back.  I saw an article on the realization of a software new departure of a USB port.  Has anyone tried this before?  If it works, I'll have to make sure I can detect an error indicating that a reboot is necessary.  Is it possible a hardware switch that I can put in line with the USB port which will create the physical disconnect with digital or software control and does not interfere with the characteristics of the physical layer?

    Thanks for your help.

    You run Windows by chance? I had a similar problem a while crossing a field of Tektronix USB. After a few hours the connection would be deleted and I had to reconnect the USB and restart LabVIEW to resume the connection. In my case, the solution was to turn off the selective suspension of USB in Windows power settings. My understanding is that Windows, in an effort to save energy, turn off USB ports apparently at random. On Windows 7, go to the Power Saving settings > change Plan settings > change advanced power settings > USB settings > USB selective suspend framework. Of course, this might be different in other versions of Windows. If you do not use Windows, then your question is probably something different altogether so feel free to ignore this message.

  • External DVD USB question

    Small question.

    Currently, using Parallels with Win7 virtual machine.  I plug in my external dvd player via the USB port to and everything is fine, but it shows in my Win7 virtual machine as a network drive with a different drive letter every time.  The software, I'm trying to run requires the CD in the drive, even where it has been installed, so it's obviously a problem.  I can't afford to uninstall and reinstall the software every time that I want to use.

    Not usb drives mount merge properly with the same drive letter every time?  Or at least to mount it as a drive off-grid that will allow me to change the drive letter in disk management if need be?

    I would like to know before you buy, so any help would be greatly appreciated.

    Thank you people.

  • iMovie 10.12 El Capitan audio question

    I recently updated my 2009 MBP Middle no El Capitan. This forced me to buy the new version of iMovie 10.12.  Since then, I have a hard time to normalize the audio tracks in an iMovie project.  How do I in the latest version of iMovie? Is there a way I can standardize all separate audio clips at the same time? Or do I have to do each one individually?

    Hello

    This iMovie help link will explain how to adjust the volume on individual items.

    http://help.Apple.com/iMovie/Mac/10.1/#/mov3b5ded23e

    You can set multiple clips in volume at the same time shift-select-the while they are selected at the same time, and then clicking on the speaker icon in the toolbar at the top of your screen.   You will see a scroll bar that when you move back, allows to adjust the volume at the same time on all of the selected clips.  It works as well for audio embedded in the video clips.

    When you work with audio, make sure that the box show the waveform is selected in the settings box you get when you click the button settings on environment right on your screen.

    I hope this helps.

  • Satellite M40-313 USB question

    Hello
    I bought the laptop that precedes the last week and I have a terrible problem with the USB ports. I connect a standard USB device such as mouse, printer, scanner etc. and everything is ok. I bought an external hard drive that is USB 2.0 and have also an old 40 GB USB 2.0 external hard drive and I can't get to be recognized by the laptop. If I plug the external sources on a PC, they are recorded immediately and work without any problem. I disabled all the USB root hubs so that the laptop can not stop devices to save energy but still the same thing.

    Can someone help me please?

    Thank you.

    Hello

    The USB ports provide 500mA. It is a standard value. If the external USB device needs more than 500mA then, the operating system can not recognize this device.
    I recommend using a USB hub with external power supply. This should solve the problem.

  • T40 USB question "this device can perform faster.

    Hello

    OS: Windows XP sp3.

    The USB is just using USB 1.1 speed and informs "this device can perform faster..." ». I googled for this issue in an hour now without solution. The driver on your page for NT4 system. Where can I find a driver to get the proper speed? Or FAQ post, just something.

    Thanks in advance

    In your research, have you been able to find this link? : http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-50838

    Even if the document refers to Windows 2000, this means that you need the latest drivers of Intel chipset for the 845 and 855 chipsets to get USB 2.0 support working.

    The latest Lenovo drivers are available from the matrix of Thinkpad here (which are always old enough):

    http://www-307.IBM.com/PC/support/site.WSS/document.do?lndocid=MIGR-46058

    I had to do something similar (many moons ago) I had on my old T40, but the version of Windows XP is come with the correct drivers, I just need to use Device Manager to update the drivers from the default values of windows to the USB 2.0 version.

    Hope that helps.

    EDIT:

    You can also find information about the troubleshooting of devices USB 2.0 here:

    http://www-307.IBM.com/PC/support/site.WSS/MIGR-4YQHUD.html

    The most useful excerpt of this link is probably:

    Ensure that the USB device is USB 1.1 or 2.0 compatible.
    Connect compatible devices USB 1.1 on a compatible port USB 2.0 will cause an error dialog box to appear. This dialog box details that a device non-haute speed was attached to a port high speed. The device must operate normally, but at a slower speed than if a 2.0 device is connected to the 2.0 port. Most of the USB 1.1 devices will operate normally in the USB 2.0 ports.

    In case, the problem is with your driver (s) machine (s) rather than the hub/port USB driver.

  • Bootcamp missing after upgrade to El Capitan

    Hi, I want to run Windows so that I can remove the ADS 'files' associated with the files I transferred to a Windows computer for Mac Pro (mid-2010) I.

    After the upgrade to El Capitan (or perhaps Yosemite, as I haven't used bootcamp for awhile) bootcamp will no longer appear when I hold 'alt' when starting.

    I use NTFS for Mac OS X by Paragon and the bootcamp partition appears in the Finder, and the files are accessible.

    I have a backup time machine in Mac OS X I have an El Capitan USB drive Installer.

    Disk0 is an SSD that would 744,91 for OS X and 253 GB of bootcamp.

    I read the posts here who have a similar problem, but my system seems to have an additional problem with a partition OS X 'extra' appearing in the readings (see below) that should not be there.

  • Mac Pro 2008 No. Startup Manager Access/Gray screen on startup

    I'm in a difficult situation and hoping a Ninja Mac can give a helping hand.

    Had a RAM issue (is no longer recognized a pair of memory modules in a 2008 Mac Pro, El Capitan), and among the troubleshooting steps, I did a PRAM reset (press / hold down ALT + CMD + P + R during startup) just to see if it could resolve. Unfortunately, the Mac would not start in front of a gray-white screen with a flashing icon of folder/question mark. Returned never me to get there.

    I had read that resetting the PRAM the disc start, among other things, may need to be reset afterwards, and this seems to be the case. Looked this solution and kept diligently press Option key during startup. This time, no folder icon, instead a sensitive cursor, but nothing else. Gray-white screen only, no boot manager to select the startup disk is suitable.

    I also tried the following...

    1. Starting in the Diagnostic Mode... Gray screen.
    2. Restore/recovery... Gray screen.
    3. Reset the SMC... Gray screen.
    4. Enter Safe Mode... Gray screen.

    OS (and apps) on flash PCI cards. All files are on hard disks in the 4-Bay, as well as a player flash remains connected to a (used as a scratch of PS) free SATA port. So I can't really share, but I wonder if I shoot all readers it would require a search for another source?

    I create an El Capitan USB boot (currently copy with createinstallmedia), but don't expect that it will offer what anyone else that its use is based on access to the Startup Manager at startup..., that I can't do. There are the graphics on the screen (missing folder icon, mobile mouse cursor) so can not imagine a video problem.

    Looking forward to enter here.

    Success!

    I created a USB bootable OS X installer using these instructionsand createinstallmedia. After some messing around with the Terminal syntax USB was ready to go. My concern, however, was that the operating instructions required by selecting the drive of the Startup Manager... which I could not access.

    With the USB stick plugged in I started to turned on the Mac while pressing the key OCCUPIED Palestinian territory and this time, the selection screen pops up showing just the USB key for installation of El Capitan. Got that we open and instead of installing I chose Startup Manager in the installation menu bar, took my normal OS drive and rebooted. Back in business, no problems.

    This put aside, although I understood that reset PRAM would also require reselect startup disk, I don't have a hot clue why did not appear the Boot Manager - or any other useful diagnostic. If someone could throw some light here would be appreciated.

    Hi all

    I am facing a problem very wired on my MacBook Pro (13-inch, mid 2009) 2.26 GHz Intel Core 2 Duo running on OS X EL Capitan, the question is on safari and google chrome, a Web site called add.ly guard popping up when I try to visit all the links, just its an ad site that saves you from 5 sec looked on this page then you can ignore advertising , but never how it keeps other ads to open in the background and really its uncontrollable. What's more annoying than that began to appear on my iPhone 6, in applications such as Facebook and formula 1, but only using my WiFi at home.

    I sorely tried several options, such as the removal of safari, firefox, and chrome; After you have reinstalled them once again, the problem is the same, I tried to use the ad, not the best blockers, I also tried avira and still make me the same question. I even tried to consult a local support engineer how had something similar and informed me that he is a spiware that might be on the ADSL router, so I had to call my internet provider and to reset my ADSL router to factory settings and to reconfigure the router again, believe it or not the issue has been resolved for about 3 hours then its back as nothing happened.
