Problems with audio/video streaming with USB devices on zero clients

Hello:
We are using view 6.1.1 in our environment and problems getting audio/video streaming to work well with the USB headsets, with zero customers.  Helmets are Jabra Link 360 and customers zero Samsung NC241.  Helmets are used as well for the phones to Jabber and also as audio device by default.   We started with the audio driver Teradici and everything seemed to work well, except that users could not answer calls on the headset itself with the button on the headset.  They were able to answer the calls of Windows though and the part worked fine.  In order to get the physical button to work, we had to first fill the USB receiver they use on the zero clients so that Windows will see as the device Jabra 360 and not the audio device Teradici.  Then we had the EHCI USB mode on them as well, and after that he started to work very well.  However, the helmets also serve as the audio device main as well as the communication (phone) device, with audio streaming continuously throughout the day.  With the current configuration, audio streaming will cut in and out during the day, and audio/video is not always to stay in either phase.

I also applied the registry in this KB hack, VMware KB: improvement in audio quality when you use speakers or USB headsets with a desktop VMware view Horizon 5.2 , which helped clear up Crackle that we originally with the part phone headsets.  But there is still the issue of streaming audio.

I wonder if the effectiveness of the bridging USB is not as effective and also is there a way to make this work better?  I read that the use of the pilot Teradici is supposed to help with audio/video problems, but do not know how that can be applied to USB devices as we use.  I've been reading upward on Teradici audio/video settings, but do not know where to go from there.  I was hoping that there are some best practices to use USB headsets with a view, but so far I'm not finding anything useful.

For any help or suggestion would be greatly appreciated.  Thanks in advance.

We were finally getting help by the people of Cisco after validation in the here and even open a support ticket with VMware, which was open for more than a month without will.  Where others try to implement similar, here are our findings:

  • Zero clients combine traffic USB and PCoIP.  It is not good when there is a lot of audio/video/USB traffic, especially the USB headsets that also carry audio softphone.  In our case, the USB traffic was so dense that it was causing audio and video become troubled and freeze and eventually cause the pcoip_server service to break in the virtual machine itself and cause the client disconnect.  The fix?  Don't use customers zero with USB phones software, they are not just designed for this type of solution.
  • Thin clients are much better designed for USB softphones.  In our case, we used the Cisco VXME client, which is the method of support for the use of Windows thin clients with the client of the Horizon.  There is integration between the two products that isolates the VOIP traffic out of the virtual machine and keeps it local on the client itself.  Regular audio and video traffic still go through the virtual machine using Teradici or VMware RTAV driver.

Hope this helps others who may run this question.  One thing we did not try was a wired headset using the AV sockets on the zero client and Teradici audio driver.  This can work, but our needs here were the headphones must be bluetooth, so we were forced to stick with USB.

  • Big problems with USB devices

    The two scenarios always perfectly work with my Mac mini that has not been updated and uses Mac OS X 10.10.

  • Problems with USB devices in Windows XP Mode on Windows 7 Pro

    I have a Palm Zire 21 that I use with ACT! Contact Manager to keep track of my appointments.  I was able to sync the Palm with my ACT database until this week. The device appears on the list of USB devices, but does not connect to Windows XP mode.

    I used this device in XP Mode since August without any problem.  Last week, I started having problems with the integration of XP features and had to uninstall and reinstall the integration features a few times.  I think I have a corrupted somewhere driver.

    Any help would be appreciated.

    No need to comment unless you have more insight.

    I solved the problem myself.  In XP mode, I went to the Device Manager and scroll down to USB controllers.  A virtualization USB bus drivers showed a problem.   I uninstalled this device and then managed to reinstall my Palm correctly after connecting it to the USB port, and then going back to the menu at the top of the XP USB mode screen and hit connect when I saw my camera.  The device connected in XP automatically and I was off to the races.

    All welcomed to this topic?

    Unfortunately the newspapers show much... (note: they do not contain client-side logs)

    one thing I thought well... since he is a computer thinClient - we have seen the questions that manufacturers computer thinClient some of their own 'management' software install on the client. He often tries to do things with usb devices (maybe try to share them between a receiver client citrix application and view client app or maybe just there is a citrix receiver application installed too). In our experience, we've seen these apps interfere between them as they try to hang the bottom of usb devices down into the kernel.

    as such, could you try stop any 3rd party services - either citrix or your provider of thin client and then try again.

    If the problem persists, can you be sure to also collect these log files from the computer thinclient:

    Windows client

    • %ProgramData%\VMware\VDM\logs\debug-*.txt
      AND
    • C:\Windows\Temp\vmware-SYSTEM\vmware-usbarb-*.log

    Linux client

    • default /tmp/vmware-root/VMware-view-Usbd-*.log
      AND
    • / Library/Logs/VMware/vmware-usbarbitrator -.log

    for reference, the Agent-side usb connects:

    • %ProgramData%\VMware\VDM\logs\debug-*.txt

  • Problem with recording devices and call issues

    Until recently I had a few problems with my microphone on Skype. Whenever I start my PC, everything will be fine, but every time I change the microphone source (from my webcam for stereo mix so I can play sounds in calls) and leave the call, I get weird questions. First if I still have the stereo mix as the source micro fine, but if I change it to my micro webcam when I click on answer call nothing happens and if I call someone it won't fail to connect and it will say: problem with the device registration, which is strange because it has nothing to do with the connection. Also if I change the source to microphone during a call, the call will be disconnected as if I turned on the internet and post something about the sound card errors. Can anyone help?

    I found the problem, clown fish was not working with Skype and it ceased to use the microphone and I thought since I had removed so I don't think that was the problem, but for some reason any, it is been installed, in any case I removed it and now Skype works fine.

    Hi MAGIC,

    It seems that you may need to update your BIOS firmware.

    You may need to contact Samsung for more information, if the update is available for download on their Web site.

    When started this issue is happening?

    You can disable the virtual WiFi adapter, as it essentially works as a tool of development at the moment:

  • IPod Classic 7 G 160 GB ' there was a problem installing this hardware: Apple iPod USB Device ".

    I have recently (June 2014) bought a brand new Ipod Classic 7 G 160 GB Model A1238.

    Whenever I connect via USB to a PC running XP SP3 and Itunes V10.0.7.2 it is always treated as if it were a new connection, i.e. "new hardware found". After trying to install it, it says so "cannot install this hardware" and "there was a problem installing this hardware: Apple iPod USB Device."
    I have also a 2009 16 GB Ipod Nano 4 G model 1285 and this is recognized by the PC whenever it is connected through the USB port itself.
    I connected the Ipod Classic 7 G to a laptop running Vista and Itunes V10.0.7.2 where the Ipod is recognized and installed.

    Even if the PC States that there is a problem installing the Ipod, it still appears in Itunes and I can download music to it and disconnect by using safe mode disconnect.

    PC XP SP3 - Ipod Classic
    I watched "Device Manager" under "Drives", the Ipod Classic is listed as an "Apple Ipod USB Device", but has an exclanation score against it.

    Right-click on the 'Apple Ipod USB Device' properties and the "Volumes" tab it shows the drive with the exact name and the size of the data, by clicking on the properties of "Driver" tab it says 'Unknown' driver provider, driver Date and Driver Version as being "not available". By clicking on the "Driver Details" properties, it shows a driver file-

    C:\WINDOWS\system32\drivers\PartMgr.sys, File Version 5.1.2600.5512 (xpsp080413-2108).

    Under "Device Manager" USB controllers, there is an entry for "Apple Mobile Devices USB Driver" and a "USb Mass Storage Device"

    The 'Apple Mobile Devices USB Driver' lists two drivers:
    C:\WINDOWS\System32\Drivers\usbaapl.sys and
    C:\WINDOWS\System32\usbaaplrc.sys

    The "USB Mass Storage Device" list a driver:
    C:\WINDOWS\System32\Drivers\USBSTOR. SYS

    PC XP SP3 - Ipod Nano

    I repeated the steps above with the Ipod Nano, connected to the PC and the driver provider is presented as Microsoft with the driver as 07/01/01 Date and Version of the driver as 5.1.2535.0.
    In the "Driver Details" properties, it shows TWO driver files:

    C:\WINDOWS\system32\DRIVERS\disk.sys AND meanings
    C:\WINDOWS\system32\drivers\PartMgr.sys.
    At the same time with the Version of the file 5.1.2600.5512 (xpsp080413-2108).

    The 'Apple Mobile Devices USB Driver' and "USB Mass Storage Device" are the same as for the Ipod Classic.

    I followed the procedure to remove Itunes and even the update to Itunes to V11.2.2 nothing works.

    I am aware that the system is also that XP can now be updated.

    So, why not not Windows Installer Ipod Classic and why the disk.sys driver does not appear

    According to the details of the pilot?

    Is the 7 G Ipod Classic not compatible with XP SP3?

    Yes it is compatible with XP SP3.

    Try asking in the forums of Apple iPod:
