  • USB 3.0 Not working in Windows 8

    Hello all,
         I have a msi 990xa-gd55 and cannot get my usb 3.0 to work with windows 8. Everything worked when I had windows 7 installed, tried installing the windows 7 drivers but they do not work. There is no usb 3.0 windows 8 driver on the download page, anyone else having this problem or found a solution?

    Are you using the most recent bios?

    Also, try a full cmos clear and see if that helps anything.
    No I am not using the most recent bios, just the one that came with it when I bought it. It worked when I had it installed with windows 7, then i had it out for maybe 3 months and built a new comp with it. Do you think flashing to the latest bios would solve the problem? It could not hurt i guess. Also, yes, usb 3.0 is enabled in the bios.

  • USB Ports are not working in Windows 7

    I am on a MacBook and I installed Windows 7 via Bootcamp. It is working amazingly. I love all the new features and the look.
    But all my usb devices are not working. I have a external HD and a Zune and a printer plugged in and nothing shows up.
    I have tried with my usb hub and without. Doesn't make a difference.
    BUT, they do show up in the Hardware and Devices place. Like I can remove them but not explore them.
    I have installed all the drivers for bootcamp and everything.
    Please help.
    Thanks in Advance.
    Best Regards,

    "I'm a new mac user and I've just purchased a Late 2009 Macbook White.

    do you have the same problem as me?

  • Why does my DVI to S Video adapter not work on my Macbook Pro since installing Snow Leopard?

    The Apple DVI to S Video Adapter worked before installing Snow Leopard.  Now I just get a blue screen.

    .wpl appears to be a Windows Media Player playlist. I can find no conversion software for that, and Windows Media Player is not available for Mac anymore.
    If you can persuade him to download iTunes and create the playlist as mp3 in a iTunes playlist, or even just burn the base mp3 files to CD as a data disc, that's about the only solutions I can suggest.

  • USB video capture not working

    I'm having trouble with Skype recognizing USB video capture devices.  I've been doing this for years and now can't seem to get it to work.  I only do this every few months, so I might have missed a post.  I have tried 4 different computers with 4 different USB capture devices, it would seem it;'s a Skype issue.  Anyone else have some ideas?  Will Skype repair the issue?
    Thanks for your toughts!

    This works for me. I have to do it every once in awhile after powering up my PC.
    It may or may not work for you.
    Open Windows Device Manager and for each Universal Serial Bus (USB) Host Controller right-click on it and then left-click on Properties. Ensure that the Device Status TextBox shows "This device is working properly." If not, Disable and Enable that USB Host Controller.

  • USB Speaker & USB Bluetooth Adapter Not Working

    hi there,
    my USB external speaker and USB bluetooth adapter (for my plantronics headset) is not working.  I believe this had to do me removing a critical program (from add/remove programs) about half a year ago - i can no longer do a system recovery to retrieve the program.  I'm currently operating on windows 7x64-bit.  all drivers are up to date and working.  the usb drives work fine - i've tried testing each slot by  connecting my external mouse and all seems functional.  it's only when i plug in the external speaker or usb bluetooth adapter that things go wrong - see screen shots below.  my internal speaker and internal mic work perfectly fine.  it appears to be only an issue with usb audio-related devices.  these devices work with other systems and computers, so i know that it is not the device itself.  i've tried uninstalling and reinstalling conexant audio, but that did not work.  i've gone into the device manager and all looks ok there. i've disabled and renabled, updated all drivers, and still nothing....any help would be much appreciated.
    thanks so much for any help or guidance you can provide.

    To find out if it's system wide or user specific, try this...
    Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
    Does it pair/work in the new account?

  • DVI to Video Adapter Not Working...

    Hi,
    I bought this thingy to view video from my Dual 2 Ghz PowerPC G5 on a Panasonic HDTV, using one of its s-video inputs. The video is blank when I switch to that input. I tried using the "Detect Displays" in the Displays preference panel. I do get a picture, but it's heavily distorted no matter what resolution I've tried - it's treated as a VGA display. Composite output from the adapter does not work at all.
    The video card is a NVIDIA GeForce 6600LE (came with the computer - two DVI outputs). Apple claims this adapter works on Power Mac G5 with DVI port, but I don't think it does. I also tried hooking it up to a VCR as Apple claims you can do, but no luck there either.
    Any advice or alternatives outside of Apple TV appreciated.

    Thanks for the technical information. That was very helpful. I took the adapter to my local Apple Store (even tho I didn 't buy it there) and asked them to test it, but they couldn't get to for a couple of hours. But, they gladly gave me a new one to try at no charge.
    As before, I plugged it into port 2 of the graphics card with an s-video cable to the tv. No success - except the picture was completely blank on the TV instead of distorted like before. Port 1 was occupied with a VGA monitor. I shut down the computer, TV, and unplugged both ports. I then moved the adapter from port 2 to port 1 and left port 2 open, meaning the VGA monitor wasn't connected to the graphics card at all.
    I turned the TV back on and restarted the computer. Lo and behold - after the booting process was done, my desktop appeared on the TV. I shut down the computer again and reconnected the VGA monitor. Ta-dah! - I now have dual monitors.
    As a further test, I hooked up the s-video from the adapter to my DVD recorder and recorded the video output from a full screen QT video to its built-in hard drive. That was successful as well. The only problem is that there is a minimal black border around the video since I was not able to pick a resolution for the TV that fills the entire screen. I may need to play with TV's aspect settings to get rid of the border, or crop it out later.
    All that's left is to capture the audio and sync it with the video, then output to my format of choice. There's my fair use copy. The quality of the video won't be as good as the original, but what the heck - I'm the only one using it anyway.
    Apple should find a way to convince TV and movie studios to sell their stuff on iTunes Store without DRM, at a higher price - like EMI is doing with their music. I would gladly pay the difference just so I could convert and burn my videos to DVD with iDVD or DVD Studio Pro.

  • Help! DVI to Video adapter not working!

    Hello,
    I bought a brand new DVI to video adapter and it's not working. I plug it in and it shows the start-up screen, but it's split screen and it's in black and white. Then, it goes into the black and white lines, not showing what's coming out of the computer at all. I've tried doing this on three separate TV's and none work. Can anyone help?

    Can you give us your video card specs and the link to the product you are using.

  • Mini DVI - Video Adapter, Not Working?

    I would like to use my standard definition television as an external display for my Macbook (late 2008 model running OS X 10.6.6), so I purchased a mini DVI-video adapter. I connected the adapter to my Macbook, then an S-video cable to the adapter, and then the S-video cable to my TV. Doing this makes the Macbook screen fade to blue then back to the regular screen, however the TV seems to not even register for it continues to show nothing. In my display settings there is a button for detecting external monitors, though when pushed nothing happens.
    I have tried to change the screen resolution and nothing happens. Also I have substituted a composite cable for the s-video cable and nothing seems to happen.
    CAN SOMEONE HERE PLEASE HELP ME SOLVE THIS ISSUE, OR ADVISE ME ON WHAT I SHOULD DO NEXT?

    Are you sure the adapter is compatible with your MB? There is a list here that should tell you if it will work or not.

  • VGA Adapter Not Working in Windows 7 (64 bit)

    I was running Win7 (64 bit) through bootcamp and could not get the VGA adapter to work.  I've tested it and it worked fine while under OS X.  In Windows 7, it could detect the secondary display, but my monitor no has signal.  I was re-install windows, but no work anytime. Anyone else encountered this issue and have a fix?

  • Apple Video Adapter Not Working

    Hi all,
    I have completed an update of 10.4.10 to 10.5 on my MacBook C2D without problems.
    I just connected my Apple Video Adapter to try out Front Row, and nothing appears on the TV! The icon appears in Displays preference pane, but nothing appears on the TV. I can change the resolution and PAL/NTSC but the TV stays blue. Was working perfectly yesterday.
    Can anyone else try this?

    On Mac Pro I use my second video out to connect a standard crt vga monitor. When I have it plugged in when I boot, the computer hangs with the blue screen everyone else has, never showing the mac os x loading screen. If I have it unplugged when I boot, everything starts fine but when I plug the vga monitor back in, it does not find the monitor after clicking detect displays. This was all working fine before 10.5, so it has to be an issue with the os communicating with my video card.
    I assume this all stems from the same issues you are having. There is a glitch in either the video driver or the new core for video that they have not fixed yet.
    I may eventually call on this, but right now, I dont have 2 hours to waste speaking to someone in the Philippines that is reading a script.

  • HP 2311C USB Monitor will not work with Windows 8.1

    Just done a clean install of Windows 8.1 on my HP Spectre XT Pro.
    The HP2311C monitor is working fine as a USB hub and the built-in Network card but will not detect the monitor as a USB monitor.
    This was working when it was a Windows 8 build and previous Windows 7 build.
    I have downloaded and installed all the HP drivers and run the HP Support Assistant to make sure everything is up to date.
    My two other collegues who have done the same upgrade with the same kit and are also having the problem.
    If we plug the HP2311C into a Windows 8 or Windows 7 machine the USB monitor works fine.
    Tried several reboots, connections and uninstalls, which have not worked. Also there are no event logs to suggest an anwser.

    I am having the same problem with my SPECTRE PRO 13 and Windows 8.1 - most unhappy about it. There is no 8.1 driver for the L2311c and I get no help out of HP as to when there might be one . These items are not cheap in NZ and I feel I have wasted my $$. It works fine on XP!

  • Apple DVI to Video Adapter NOT WORKING

    So I have this mac pro but no monitor. I went to the apple store and bought the Apple DVI to Video Adapter. I hooked it up and turned the computer on and there's nothing showing up on the screen(TV). Why is this happening? The whole point of this adapter is to not need a monitor.... do i need a monitor to set it up?

    Why don't you click on the Apple icon at the top left of the screen.
    Select About This Mac. Click on the info about which version of OS X you have - under the Apple icon - click twice to see your serial number. Use it to determine the model of your Mac Pro on Apple's web site. Inform those who would help you what model Mac Pro you have.

  • Apple DVI to Video Adapter not working with SL + Mac Mini

    I've seen some issues with the video adapter putting out only black and white signal with Macbook Pros. That would be an improvement for me.
    I can't get SL to play with the video adaper when I plug it into my TV. I get black and white and a bounching broken up signal, as though the refresh rates don't match. I can't play around with the settings because it's impossible to see what's on screen. I have to plug my monitor back in.
    This used to work fine under Leopard.
    How will I ever watch Mad Men now?

    Why don't you click on the Apple icon at the top left of the screen.
    Select About This Mac. Click on the info about which version of OS X you have - under the Apple icon - click twice to see your serial number. Use it to determine the model of your Mac Pro on Apple's web site. Inform those who would help you what model Mac Pro you have.
