    Hi,
    we’re looking into using the new R10 model from Wyse with our Citrix XenApp 6 platform. Our main goal is to get a new perspective regarding multimedia, spesifically video conferencing.

    What I’ve learned so far is that ThinOS 7 and XenApp 6 have the capabilities to connect with the local webcam. Does anyone know if we need TCX to do so or have I missed a configuration step in my WNOS.INI, because we cant seem to get this working…

    Short: I’m looking for a way to connect my local webcam to a citrix session with a wyse thin client. πŸ™‚

    Anyone?

    AFAIK ICAHDX for XenApp doesn’t allow to redirect webcam. TCX can do this but in SHARED mode – i.e. your webcam will be seen by ALL users of the particular terminal server. Hence – problems. From the other hand both TCX and HDX (you don’t need TCX in this case) for XenDesktop (I suspect you purchased XenDesktop licences πŸ˜‰ ) redirect webcams. ThinOS 7 has very good support for HDX redirction. I tested Skype and other video apps on V10LC10LE with XenDesktop and HDX redirection – it is OK.

    Thats actually incorrect, as Citrix XenApp 6 with Citrix Xenapp Client 12 fully supports webcams. (http://community.citrix.com/display/ocb/2010/04/05/Best+Practice+for+delivering+Microsoft+Office+Communicator+(OCS)+using+XenApp+6) I have got it working with my laptop, so I know the configuration on the Xenapp servers are correct…

    That aside, how did you configure your V10/C10 to get the webcams to work? If I understand you correctly, you do not use TCX?

    To use a webcam in that kind of environment you would need to have the webcam driver installed locally on the client as well as on the server site.
    As you know it is not possible to install any kind of driver locally on a WTOS device.
    Therefore you would have to use a supported webcam. This is the Logitech 9000.
    Get your hands on this cam and it should work.

    Well, this is the best suggestion so far πŸ™‚ I’ve done a couple of tests with the 9000 Cam, but only to discover that the same applies to that model also… It could be to the fact that the 9000 model lacs the support for W2K8R2, although I was able to install the drivers by picking up the installer in the %temp% directory.
    Is this the only modell available?
    Am I missing a configuration in my wnos.ini? (tried Device=Vusb Type=HDX to no avail, the same goes for UnMapUsb=Yes)

    1)XenApp Client 12 is not available for ThinOS – it is for Windows client 2)its webcam support is not a kind of USB redirection but of something like ICA TWAIN redirection – i.e application object redirection while we are talking about USB redirection.

    There was a problem starting webcam (even with TCX) on W2003S since Windows Image Acquisition service is down on server OS by default. Maybe the same is with W2K8S?

    I used ThinOS 7 HDX (ICA) support and VM WinXP under XenDesktop and there both Logitech 3500 and MS VX-800 worked ok. Where I had problems with XenDesktop was Win7..but due to MS recognised problem with Logitech drivers
    V10LC10L were configured as XenDesktop clients (broker) and had HDX redirection selected for USB redirection. XD policies had USB redirection allowed and applied to all users.
    Oh..there was a problem we didn’t manage to solve – webcam mic rejected to record sound, we had to use regular mic.

    You where quite right about the WIA service, it was set to automatic but was’nt started. Starting it did not help either, when it stops automatic after a minute or so.

    I’m beginning to think that we cant get this to work and that webcam redirection is not supported without TCX with XenApp 6. I tried the Pro 9000 but to no avail. It looks like it doesn’t recognize the unit as a webcam (just says “Found new device “Wyse vUSB” in port x”) Anybody beg to differ? πŸ˜₯

    WIA stops? – really don’t know the reason – sorry. Maybe this is server role dependent?
    You should have in the logs smth like
    38: USB: Found a new device “WYSE VUSB” on port 6
    39: TCX USB: Redirect device on port 6

    You need to add forceredirect command to wnos.ini if device is not redirected.
    What I would do in your case – I’d start trying to add webcam to virtual WinXP with TCX and RDP (the most simple configuration for USB redirection IMHO) and watch results. If it is OK continue with your setup. If not – almost 100% probable it will not work in more complex configuration

    We do not use TCX so step 39 would not apply to us. As for the ForceRedirect, I was looking for the Local Device ID but did not find anything after it actually found the device.
    Anyways, I’ll give it another go and check again πŸ™‚ I’ll report my results.

    Thank you everyone for great advice so far πŸ™‚

    Tried using the following WNOS.INI config to no avail:
    Device=vusb ForceRedirect=0x0a12,0x0001,0xe0,0x01,0x01 Type=HDX
    Device=vusb ForceRedirect=0x148f,0x2770,0xff,0xff,0xff Type=HDX

    I’ve heard that Webcam rederection on the current WTOS to XenApp 6 is not supported for the moment.

    WTOS 7 MR1 planned as a January update will also support this HDX Realtime Webcam feature. This feature is quite CPU intensive so while C or V class may be good at certain resolution and FPS, the new R10L is recommended for best results.
