El Capitan USB port does not worked well under Yosemite.

Running a VMWARE image of the Linux kernel using a Sentinel of SafeNet USB license dongle canned.
Has worked perfectly under Yosemite unfortunately too long to go back.

The USB port does not work with other USB devices?

I suspect an incompatibility with the EC and the sine of dongle USB EL strengthened using third kexts. They must be signed, and so a softer update for the dongle is probably necessary.

    If everything is OK and right drivers all USB ports should work. You cannot install the drivers for each port separately and force one of them to work properly. On this machine, all three ports are the same USB2.0 ports.

    Try reinstalling the chipset utility.

    By the way: two other ports work well, right?

    > This problem start after a storm in my area some time ago.

    Because other devices don't work properly and because procedure didn t get it back help you solve this problem, I think that the problem is related to the hardware malfunction possibly that the motherboard was hit by lightning, which would explain the problems

    I think you should ask the maintainer authorized Toshiba in your country to check the motherboard.

    But in my opinion, that the warranty does not cover the issues of environmental impact maybe your household insurance could help you

    If the USB ports are properly recognized in device then as Quad Manager said it could be an external problem. The USB port is 500mA power. If the external device requires more power to work in this case, it of necessary to use the external power supply.

  • A 'Powered USB Port' does not work on Mac Mini

    I have an external POWERED USB multiport block. When I plug the Superdrive into a Port powered on the unit, which of course is connected to my Mac Mini (2012) the Superdrive not even she acts as if it is connected and will not accept a disc. All ports are USB 3.0. I'm so uncertain that the Superdrive will work on any USB port other than the one on the Mac itself. Any advice?

  • M40-265 - 2 of 3 USB ports does not work

    Hi all

    Since yesterday, I have my Toshiba Satellite M40-265.

    My problem is 2/3 ports USB does not work.
    I've tried different USB devices such as memory stick, mouse usb and usb printer plugin.
    Just plug the device into the left USB port, if they will be recognised by windows xp home.

    Any ideas what's wrong with my laptop?



    Hi Gerold,

    It looks like a hardware problem with your USB port. Visually check the ports that do not work and you should see a central plastic ankle against which should be four strips of copper fitting. Make sure that none of the tapes is twisted or damaged, it is quite common for one or several of them have been accidentally bent out of position or ankle Central plastic must be broken.

    Kind regards

  • My usb port does not work. Device Manager says he has a "code 10".

    My dad recently bought a laptop on ebay. It's a HP Omnibook 900 with a 4 GB HD. The previous owner had improved from the original from Windows 98 to XP with SP3.

    It has a USB port in the back & it does not work!

    In fact it is not even appear in the Device Manager! I need to select 'Show hidden devices' to see same the USB hub root. The USB port has a yellow warning icon. In properties, it indicates the port is enabled but does not work because of a "Code 10".

    What the devil is a "code 10" & how in the heck to solve this problem, so that the USB works?

    The port is powered. When I connect devices usb load they turn on & load, but, of course, are not displayed on the computer. My best theory is that the port can be usb 1.0 but the software is intended for usb 2.0 and what could be the cause of the problem. That's just guessing on my part because I do not know with certainty if the usb is 1.0 or 2.0.

    It is especialy boring being the only external devices can I plug a CD player (unwritten) & a floppy drive. It would make my life much more pleasant if I could run software, backup & file transfer, etc. with a usb drive instead! It could even than the laptop quite useful to be worth the bucks thirties, my father paid for it!

    Help, please. Thank you.

    Hi SnarFoo,


    The Code 10 error code is generated when Device Manager it has not enough information or error that has spread upward through the device drivers is not recognised by the Device Manager. In addition, this error may occur if one of the pilots who needs the unit does not start. If multiple drivers are used by a particular device, it can be difficult to determine which failed.

    See the article and check if that helps.

    Description of errors related to the 10 Code that generates the Device Manager in Windows on computers


    Method 2

    If the previous step fails, then remove and reinstall all USB controllers on the computer and check if that helps.

    To remove and reinstall all USB controllers, follow these steps:

    (a) click Start, click run, type sysdm.cpl in the Open box, and then click OK.

    (b) click on the hardware tab.

    (c) click the Device Manager button.

    (d) expand Bus USB controllers.

    (e) right click on each device under the Bus USB controllers node and then click Uninstall to remove them one at a time.

    (f) restart the computer and reinstall the USB controllers.

    (g) connect the removable USB storage device and perform a test to ensure that the problem is solved.

  • USB ports does not work

    I intend to reset my laptop to factory settings by having the PC clean up the hard drive and reinstall Windows 8.  Before I do, I'm copying the files on my flash drives. I have a moment (I'll call him 'A') is a 32GB (brand new, he got today) which is/has been formatted with diskpart (so I can use it to create a recovery partition).

    About 78-80 percent of the formatting of diskpart, I put in my latest flash player (I'll call it 'B') to copy some various files that do not have to be copied, but thought I'd for a while once the laptop has reset.  Unfortunately, as soon as Flash Drive 'B' has been plugged in, my mouse work anymore (so I just unplugged thinking the battery died), and the laptop does not save Flash drive 'B '. I tried to put the other 2 ports USB that were not used, same thing, the laptop does not save it. I refused to get out of Flash Player 'A' because it is / was still formatted with diskpart. I checked the file Explorer, and the two flash player 'A' and 'B' were not under 'computer '.
    Fortunately the files I really need to be backed up, are. So, I'm ok with that. Oh yes and I tried to put in flash players, and they were not recognized by the laptop.
    Couple questions:
    (1) Will Flash drive 'A' be affected in any way since it was "unplugged", while being formatted with diskpart?
    (2) my laptop isn't even a year yet, then how/why would my just closed USB ports?
    (3) is it possible that all 4 ports could just die at the same time random?
    (4) I really hope that's not it, but my motherboard could be beginning of failure?
    My laptop is an ACER Aspire V3 771 G, 1 TB HDD, NVIDIA GeForce GT730M, 8 GB of memory (4 dedicated for video) DDR3, Core i7 and running Windows 8 and I have had since about June of 2013. Main uses are for some school work dealing with CADD, game on PC via Steam, YouTube and Netflix occasional streaming movies via a 3rd party source that so far has given me problems such as viruses and bugs.
    I'm going to try to uninstall the USB controller drivers and reboot the laptop, unplug the power and take the battery method, simply by restarting the laptop WITHOUT uninstall the USB controller drivers. I'll try these stars and come back to say if either one of the fixes worked.
    * Real quick as question 1. USB key "A" literally just a finish is put in shape and when I entered the command 'assign', that the flash drive has been recognized once again, until I quit diskpart, now it is not yet recognized and even goes with my other, and my mouse (which the battery is NOT dead).

    Well, I would just put it out there, it was just a hiccup. I went to the stop of the laptop and he "fell on a problem" and instead start again, he drilled in reactivating the USB ports.  They all work very well. YAY! :)
