USB Support in Hyper-V. Very Confused.

I am running Windows 8.1. I start Hyper-V and need to install which Operating Systems to have USB support inside of the VM? Is this possible? I tried windows 7 and I do not see Enhanced Session Mode. I tried windows 8.1 and again I do not see Enhanced
Session Mode. Is it possible to have USB access in a Hyper-V VM?

Hi Sir,
Client hyper-v needs the host OS is x64 win 8/8.1 Pro/Ent :
http://technet.microsoft.com/en-us/library/hh857623.aspx
Enhanced session mode comes with win8.1/server2012R2 , also the guest OS should be 2012R2/win8.1 :

  • I have installed the new up to date itunes which i can open on my PC, however when i connect my ipad or iphone i get an error saying i cannot use the device as the require software isn't installed?? I'm very confused please help......

    Let's try a standalone Apple Mobile Device Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of why it's not installing under normal conditions.
    Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
    http://www.apple.com/itunes/download/
    Download and install the free trial version of WinRAR:
    http://www.rarlab.com/
    Right-click the iTunesSetup.exe (or iTunes64setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
    Go into the folder and doubleclick the AppleMobileDeviceSupport.msi (or AppleMobileDeviceSupport64.msi) to do a standalone AMDS install.
    (If it offers you the choice to remove or repair, choose "Remove", and if the uninstall goes through successfully, see if you can reinstall by doubleclicking the AppleMobileDeviceSupport.msi again.)
    Does it install (or uninstall and then reinstall) properly for you? If so, can you get a normal iTunes install to go through properly now?
    If instead you get an error message during the install (or uninstall), let us know what it says. (Precise text, please.)

  • HT1444 The update vs. upgrade paths are very confusing. I'm running OS X v10.5.8. What upgrade products do I need in order to become current?

    The update vs. upgrade paths are very confusing. I'm running OS X v10.5.8 and trying to figure out what versions I need to purchase/download in order to become current.
    Thank you!

    Phone the Apple Store, order a Mac OS X 10.6 DVD, and run Software Update. If your Mac supports it, buy 10.7 or 10.8 from the Mac App Store.

  • Java usb support for  windows

    Hello All
    I do no know if this is the right place to post this topic, but does anyone know of an api that provides usb support for windows. I was looking a jusb, but the documentation says it only has support for linux. So far the best I have found is Mr Stahl's thesis which provides very limited support for windows. I was wondering if there was anything more stable (free or not)
    Thanks

    Hi,
    Im trying to connect 2 computers using USB or Parallell port. On one computer I want to install a printer (regular windows printer) that prints through either USB or the Parallell port. On the other computer I want to listen on the Parallell port/USB port and receive the input and write it to a file.
    Does anyone have a some sample code to do this? I've tried the following code (rxtx) but it cant find more than 2 ports (one parallel and one serial - no USBs even though I have 5 USB ports). Since I could only find the USB I tried to listen on the Parallell port. Problem is that I dont receive any data.
    <---THE CODE--->
    Enumeration port_list = gnu.io.CommPortIdentifier.getPortIdentifiers();
    while (port_list.hasMoreElements ()) {
    CommPortIdentifier port_id = (CommPortIdentifier)port_list.nextElement ();
              if(port_id.getPortType () == CommPortIdentifier.PORT_PARALLEL) {
                   System.out.println("Found port "+port_id.getName()+ "id "+port_id);
                   CommPort commPort = port_id.open("",2000);               
                   InputStream is = commPort.getInputStream();
                   byte buffert[]=new byte[1024];
              int len;
              System.out.println(">>>>>>>>len "+is.read(buffert));
              while((len=is.read(buffert))==-1)
                   Thread.sleep(500);
                   is = commPort.getInputStream();
                   System.out.println(">>>>>>>>len "+len);
    }

  • Need Chipset Driver for USB support

    Hi.
    This Windows XP-SP3 PC has 4xUSB2 or 2xUSB3 on-board ports, and all have failed. All USB devices are yellow-flagged in device manager.
    I have run SFC \SCANNOW and it runs to completion, and I have tried right-clicking on a yellow-flagged USB entry in Device Manager and selecting Update Driver, but that only results in the following dialog:
    Cannot Install This Hardware
    There was a problem installing this hardware:
    Universal Serial Bus (USB) Controller
    An error occurred during the installation of the device:
    The driver installation file for this device is missing a necessary entry. This may be because the INF file was written for Windows 95 or later. Contact your hardware vendor stop
    It has been suggested to me that I should try to obtain the Chipset Driver for USB support. Running Speccy reveals the following about the mainboard:

  • Very confused with iTunes Store issues

    Dear all,
    I am a Mac user who owns several mac computers and several iOS devices.
    I have become very confused over my rights concerning my specific Apple iD.
    I understand that when purchasing DRM free music from iTunes (256 bit - it appears as Purchased AAC audio file) on my main Mac computer, then I can play this music to as many computers I have, not only 5. Is this correct?
    I remember at some point that on one of my other Mac computers ( my secondary computer - a Mac Mini) I was able to listen to my music purchased, in the past, on my main computer, by having it streamed (not downloaded) from the iCloud onto my secondary computer. Somehow this has been lost recently. Now I am faced with the task to authorise my secondary computer, which I cannot do, because I have 5 computers already authorised.
    What am I doing wrong?
    Has iTunes 11 changed anything in this respect?
    Any help will be most appreciated.
    Merry Christmas and best regards
    Andreas

    I had tried all these, deleting 'Downloads' folder in 'iTunes Media', creating a new user (administrator) account and downloading movie with the new account, following error -50 trouble shooting steps, but none of them worked. I did contact iTunes customer service. In addition to what listed above, they also suggested I download the movie using another computer and transfer the file to my macbook air, which has nothing to do with my problem at all.

  • 915P Neo2 Platinum v1.0 USB Support

    I am having problems with my USB support under XP Pro.
    I have 2 front USB ports, 4 on the motherboard, and 2 on the extender cable at the back.
    When I connect a USB2 device to any of the non-motherboard ports, the PC freezes and is not recoverable (except for reboot). USB1.1 devices work fine in any port, and USB2 devices work fine in the 4 motherboard ports.
    I have the Intel® ICH6R Chipset for USB support, with the latest drivers installed.
    I have also checked the cable pinouts for the two USB connectors to the motherboard, which all look ok.
    Is this a problem of the motherboard, or the OS?

    Thanks heaps Danny for the info. The Wonkanoby link is what I needed.
    A quick snip and up she came. All USB's are now working perfectly.
    Antec Sonata case by the way!
    (I'm obviously not the first here)
    Very informative link. Thanks again

    There's a whole lot to read in your post, and frankly I have not read it all.
    Having said that, this troubleshooting guide should help:

    In particular, pay attention to the mobile device support sections near the bottom, assuming you have already done the items above it.

    On your Mac, try to access your gmail account. There should be a link you click for "Forgot My Password". Click it and try to retrieve your password.

  • I am very confused. When I wanna to update my apps in app store, it shows the account which is my iPhone one is not my iPad one. how can I reset to my iPad account?

    I am very confused. When I wanna to update my apps in app store, it shows the account which is my iPhone one is not my iPad one. how can I reset to my iPad account?

    And I am very confused by your query. Your iTunes account is the same on all devices - unless of course you have multiple accounts to begin with.
    If you do have another Apple ID that you use for the iPad purchases, you can sign out of the account that is on the iPad in Settings>Store.
    Perhaps a few more details from you could clear up the confusion???

  • 10.6.8 Update - No USB Support - Help!

    Early 2008 MBP under warranty for another 34 days. Nothing interesting installed beyond usual Mac, MS and Adobe software. Occassionally run Parallels 6, but not today and not recently.
    At 9:00 was offered the auto update to 10.6.8. Closed open apps and let the MBP do its thing.
    On reboot the usual screen came up but there was no trackpad or keyboard support. Was able to use a bluetooth mouse and all apps opened but still unable to type anything or use the trackpad mouse. Also noted that there was no USB support for an external drive, or keyboard (or I would have tried to roll back to 10.6.7 with Time Machine.
    Rebooted multiple times with the same outcome.
    Spoke to Apple and they had no suggestions except to get warranty help. Well that's 50 miles away (service provider, not an Apple store). Any suggestions to save me two trips (there and back to deliver and pick it up)?

    I have a early 2008 macbookpro 2.8 duel with silver keys.
    I purchaed the 10.6 disk from the apple store. I've had the machine for years and purchased it refurbished from apple.
    I did the erase and install and migrated everything over from external drive, then did update to 10.6.8 and the usb ports still would stop working after a few hours.. Then I read on another apple community forus to reset pram, and pull out the power cable, take out the battery and hold power key for 5 seconds, then restart. that seemed to fix usb issue so far..
    But overall my computer seems to be running slower then when using just 10.5.8 and it did not wake from sleep once and I had to force power off and restart.. But maybe its just getting used to 10.6.8. we will see..
    Also, on another note, my battery is totally dead, and I can only run computer with power cable.. Will this affect things? it never did with 10.5.8..
    Oh, on my erase and install, I just did the simplest version and did not do the full erase to zero using he advanced security measures.. I just did the one where it writes on top of everything..

  • Solaris 10 Oracle VDI VirtualBox 3.2 USB support

    Dear folks,
    This my first time to the forum, since we are in the progress of deploying 240+ thin clients using Oracle VDI. I was piloting the project in a desktop machines with Sunray 3i. I installed Solaris 10 9/10 and Oracle VDI 3.2.1. However, while I was creating WinXP VM in Virtualbox 3.2 -the one which came with Oracle VDI 3.2- I got that error about being unable to connect to USB proxy server. Eventually this error leads to that all my VMs doesn't support USB redirection. So USB flash disk drive doesn't work in my Sunray 3i. Reading VirtualBox documentation Installing on Solaris hosts , I came across this info "*This does not apply to Solaris 10 hosts due to lack of USB support.*" Is this real?
    Does this mean I can't redirect USB hardware to my VMs in the server via Sunray 3i? If this is true, what is the workaround for this problem?
    Please advise me. . .

    Other than the documentation stating it doesn't work, in practice have you tested it to not work also?
    We have two Solaris 10u5 machines running Vbox 3.2.12 and they pass through USB fine with our Sun Ray 3's (not 3i's but that shouldn't matter).
    Did you enable USB passthrough in the VDI core by selecting the desktop pool and going to the Settings -> Sun Ray RDP Settings? Theres checkboxes to enable USB/smartcard pass through.

  • What exactly is the difference between the new photos app for mac and iPhoto? i'm very confused...

    Ever since i've bought my macbook pro i used iPhoto to organize my photos. Now apple added this new photos app and i don't really understand what is it meant for? can someone please explain me the difference? I'm very confused about the purposes of both apps....

    Now apple added this new photos app and i don't really understand what is it meant for? can someone please explain me the difference? I'm very confused about the purposes of both apps....
    Photos is a completely new designed photo application, designed for Yosemite and the MacOS X versions to come. Many differences are under the hood. It uses the new system libraries and frameworks for more efficient image processing on the new powerful macs, like the mac pro, it is extensible by app extensions, if other developers will add functionality, and most important, it brings integration with iCloud Photo Library. With Photos you can store your photo library in iCloud and sync it across all devices.
    Some features are still missing however, and you can continue to use iPhoto, if you like. Or create a small Photos library for testing and explore Photos, while keeping your main libraries in iPhoto.
