After my last OSX update: usb ports not working on my apple numeric keyboard

I'm curious if anyone else has lost usb connectivity on a Apple numeric keyboard after the last OS X update. I get the error msg "USB device needs power, connect usb disk (jump drive) to power or a usb port on this Mac". I am using OS X 10.9.1 (13B42) and the last update I took was iMovie 10.0.2 on Jan 25, 2014 on an 27' iMac (late 2012) i7 3.4 GHz, 3TB fusion, 32Gb RAM, GeForce GTX 680MX 2048MB video. All four usb ports are be used and are active on the back of the iMac. All I need is the occasional acess to a couple of jump drives via the keyboard ports. I have just ordered a 3.0 powered usb hub (Satechi) This will soon be a non-issue, but I know it used to work and I'm thinking that the OS X update might has done something to my keyboard ports. Anything?

The keyboard ports are usually slower transfer rate than other ports, so would likely be unsuited for use with flash or USB storage. There is usually an upper limit to the system load of all the ports together, perhaps that load is near the maximum already, too.
Hopefully the powered USB hub will resolve the issue.
Good luck & happy computing!

Hi,
What about if you try to install drivers from your product's page?
http://uk.msi.com/support/mb/Z97-GAMING-5.html#down-driver
And when exactly it starts to fail to work? Did you try to have OS just installed, restart it and see if it works then? Are you able to determine which driver installation causes USBs to stop working?
thank you
i just remove USB3 controller driver and work
thank you all :D

After doing a widows update itunes will not work at all

after doing a widows update itunes will not work at all

hiya!
I get the itunes has encounterd a problem and needs to close, sorry for the inconvenience error, no specific error number. I do not have QT installed,
not having QT installed is what will be causing your itunes error message at the moment. let's try a careful standalone QT 7.1 install.
download and save a copy of the QT 7.1 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
Quicktime 7.1 Standalone Installer
if that install goes through okay, does your itunes launch properly again?
(if you get an error message on the QT standalone reinstall, let us know what it says. include error message numbers if you're getting any.)

Touchsmart TX-2 fingerprint scanner and USB ports not working

Hi everyone,
Please forgive me if this is in the wrong spot.
Just sent my laptop (Touchsmart TX-2 1015au) off for a warranty fix - told them the USB ports weren't working on Windows 7, 64 bit. It came back wiped, running on Vista 32 bit and.....with the USB ports not working.
I figured I'd try to get it working because I need my laptop for uni and can't send it back right now. So I clean installed Windows 7, 64 bit again and its still not working. Did the standard open device manager and uninstall everything under the usb tab. All that has resulted in is causing the fingerprint scanner to stop working (being told that it is not connected) and still no working USB ports.
All advice really welcome and very much appreciated!
Thanks in advance

Hi:
Should be no problem to get W7 32 bit to work on that model.
Just use all of the drivers and software from the HP Probook 450 G0 on your model except the Audio, BIOS and firmware files.
Your model uses the Intel HD graphics driver only.
The first driver you have to install is the Intel chipset installation utility and then reboot.

USB ports not working after OSX 10.9.1 update

I have a late 2011 MBA 13".
The 2 USB ports stopped working as soon as I updated to 10.9.1.
I tried zapping PRAM and resetting the SMC.
I even turned the thing off for hours and still nothing.
Any idea how to fix?
Everything was fine until I did the update.
Thanks.

This is not a known bug affecting 2011 MBA computers with 10.9.1 so there is something wrong with your installation. Since zapping PRAM and resetting the SMC did not work I suggest that you try one of two things but first make sure you have backed up your computer.
1) download Mavericks and reinstall it. Sometimes an update goes awry and a reinstall fixes it. Since doing this won't disturb any of your data or applications it would be my first choice. You'll be downloading 10.9.1 so you won't have to perform any updates.
2) boot into the recovery mode, erase the hard drive and then download and install Mavericks. Once Mavericks is finished installing you'll be asked if you'd like to migrate data and applications from a backup. Say yes and if your backup drive isn't already connect it, do so. Select your applications folder and account folders from the list and let the Setup Manager do its magic.
BTW - this is why one of my several backup hard drives is a cloned backup using Carbon Copy Cloner (SuperDuper! Is another good choice). I can boot up my computer using this backup and download the newest version of Mavericks on it if I haven't already done so. I always quit the installer first and make a copy of it because the installer program deletes itself once it is finished which is something of a pain. It gives me more options including being able to boot my computer with it, erase the computer and copy the installer to the computer rather than having to perform the download all over again if step 1 fails. Since I always download a new copy of the OS when Apple releases an update this computer will have the newest version of the installer so I also can skip the download step of option 1 and just copy it over and install on the computer.

Front USB Ports NOT Working

Really need help from the experts here ------ HP Pavilion Slimline s5-1 Desktop Model: H2M46AA (has Joshua mainboard with Intel H61 Chipset) Hard drive crashed and have no original drivers. Did clean install of Win7 SP1 Home Premium. All OK except Other Devices, Universal Serial bus (USB) Controller. Driver cannot be found. After the Win7 install, installed an ethernet driver and then from HP website installed the Original Chipset files. All drivers OK except the above which apparently controls the front 2 USB ports which didn't work. Next, installed all updates provided by Windows Update. Front USB ports still inoperative. They worked before the new Win7. After much research, inoperable front USB ports appears to be a common problem, but none of the provided solutions help (check cables, power down completely, Intel Driver Update Utility, etc.). On my system, the first of 4 Hardware IDs for this device show as: PCI\VEN_104C&DEV_8241&SUBSYS_2ADA103C&REV_02. According to pcidatabase.com, this is identified as: "Texas Instruments USB 3.0 XHCI Host Controller", and thus a possible the problem. The ports are, I believe, USB 2.0 and not 3.0 according to Joshua documentation (http://www.foxconnchannel.com/ProductDetail.aspx?T=motherboard&U=en-us0000525 Also, review of "\windows\inf\setupapi.dev.log" shows there are no files on the drive associated with the above Hardware ID because they cannot be found during driver installation. So question: How can I get these USB ports working -- have installed every recommended HP update for this system. I'm stumped!

You're right, it's just an update of the driver but I think it is specified, you can see theTechnical Reference: ftp://ftp.hp.com/pub/softpaq/sp70501-71000/sp70786.html TITLE: Texas Instruments USB Controller Driver Update

It is only a piece a equipment; any part can break at any time. You may want to contact HP technical support and identify your options. These options will be based on your warranty status, and you can locate that information here: http://h20566.www2.hp.com/portal/site/hpsc/public/wc/home?ac.admitted=1383763792097.876444892.199480...

V570 - USB Ports Not Working

Please forgive me if I posted this in the wrong section! First thread!
Recently, three out of four of my USB ports decided to stop working. The one USB port that works is a USB 2.0 port that is located between the microphone jack and the DVD drive. There is also a eSATA / USB combo port. The eSATA portion works fine, but the USB does not work. At first I suspected that the USB controller was probably starting to fail. I don't understand why all but one USB port functions properly.
I have tried reinstalling the chipset drivers, updated my BIOS, and I tried to see if the ports are recongized in Linux. None of those work. I also checked the ports to make sure there are no bent pins. My warranty period just ended so I was wondering what I can do now. I don't mind opening up the computer, as long as I know what to look for.
Thanks in advance!

hi idaggerpwn,
The USB board must be bad. Try to re-seat the cable from the USB board to the motherboard and check. If this doesn't work, check if the USB ports are somehow disconnected to the PCB. If they are, you will need to hire an a technician with board level soldering skills to reconnect them or you can contact lenovo for service to replace this part. (fees may apply)
Check page 78 (see #10) of the hardware maintenance manual (HMM) for the USB board location. To access the USB board see page 53 of the HMM.
Best regards,
neokenchi

G580 (2189) USB Ports not working

Hello,
I have an ongoing problem (for 2 months, before I had no problem at all) with all 3 USB ports on my G580. None of them are working properly, if I plug in a device they do not recognise it, however, the devices get power, e.g. I can charge my mobile phone through USB port but it does not recognise it. The most irritating part is that also my opctical mouse does not work.
I have tried a couple of solutions like:
- restarted the computer
- uninstalled the USB root hub, devices etc
- disabled the above mentioned ones
- ultimately I refreshed the OS (I have 64 bit Win 8.1) but the problem still occurs.
I attached a picture.
Thank you for your help in advance.
Balázs

hi Balázs,
Just to check, was this G580 (2189) originally running on Windows 7 as indicated in this pdf datasheet? If yes, were the USB ports working fine before you upgraded to Windows 8.1?
If the USB ports were working fine before the upgrade then it's likely that this is an OS issue as discussed in this microsoft blog.
Things that you can try:
1. Run Windows Update to get the latest patch and bug fixes for the OS.
2. Check this microsoft blog on "What to Try When Your USB Device is an "Unknown Device"
3. Check this microsoft blog on how to apply a registry workaround.
Hope you get the issue sorted out.
Regards

Installed Windows & 32 Bit But Drivers and USB ports NOT WORKING.

I bugh an HP Pavillion TS 14 Notebook that came preinstall with Windows 8.1 64 bit which I hate so wiped the drives and installed Windows 7 32 bit and now I have a big problem. None of my network drivers work and the 2 uSB ports where I plug my mouse and other SB hardware in no longer work.
I did a back up of the SW Set up file that has all of the HP dvers for my laptop but both the network and video divers won't install. And When I try to install the drives I get the eror message saying they are not compatible with this version of Windows.
I have loked on the HP website under my laptop model which s as above but HP don't do drivers for Windows 7 32 for my laptop. And I have looked on both the Realteck website for both the Realteck ethnet and Realteck wireless network drivers but none of them work or install on my operating system. The video drivers Intel don't work either. So I am really stuck a I cannot go back to Windows 8.1 as though that 32 bit Windows 7 would work on my laptop but most of my drivers are not compatible with the operating sytem And I don't want to install 64 bit Windows as I like 32 bit.
The drivers that are not working on Windows 7 32 bit are:
Realteck RTL8188EE 802-11b/gn witeless lan
Realteck ethnet die and
Intel High definition graphcs driver
Which don't work at all on Windows 7 32 bit as they are 64 bit only drivers.
So can you please post me a link bth the network and Intel graphics drvers that work with my laptop. As I have tried lots of different Realteck and raphics drivers for Window 7 but NONE of them work on my system. And None of my USB ports are working either. So how do I solve this problem?
This question was solved.

USB ports not working in safe mode

I am trying to back up my computer before i take it to the apple store and i cant back up in safe mode using time machine, becuase im guess the USB ports arent working. Are there any solutions to this problem?

Ok, where is this Intel driver? There is no such thing "program manager" so I am guessing you mean the Programs and features control panel, but on my machine that whole window is blank after a clean install. I still cannot get the USB ports to activate. Two fresh installs and several different USB sticks later and no luck. Should I just give up and go to Windows 8.1? I really need Windows 7 to work if at all possible. Other devices shows one USB controller without driver software so I suppose that's the culprit. There are other USB devices installed under the USB section of Device Manager, but they apparently have nothing to do with the USB ports themselves, just devices like the trackpad etc. I've spent two hours on this so far and it's getting out of control. Why doesn't this work with generic USB drivers?

Split x2 problem with USB ports not working

My computer is somewhat new and this problem has been happening since I first got it. I couldn't find anything about this problem here or elsewhere online.
When I plug anything into either USB port (I've tried my phone and an external harddrive) the computer like sort of recognizes it on and off. When I plug in my phone the computer beeps at random every several seconds and doesn't recognize it. The external hard drive was sort of recognized but only on and off and I couldn't move things from it to my computer because it wouldn't stay connected long enough. It's literally like every 2-3 seconds it recognizes the USB thing, changes it's mind and then recognizes it again, etc. forever.
I haven't had a chance to test the SD card slot or the HDMI port yet.
Sometimes the mouse freezes also, I'm not sure if this is the same problem (related to connection between the tablet and the keyboard parts) or if these are separate problems. It seems to be happening less often and goes away if I wait for a moment. Still annoying but the USB ports not functioning is a more urgent issue.
I need help, is there a way to fix this or is something faulty with my computer?
