Secondly the use of webcam can be configured within the Citrix Workspace App (formerly known as Receiver or Citrix client). This can be done by the user out of the Desktop Viewer Preferences. Especially in the COVID situation many people are working from their personal home system where we cannot arrange that yourself. Webcams can be used by video conferencing applications running within the virtual session. The application on the server selects the webcam format and resolution based on the supported format types.

Looking for webcam configuration help on Wyse 3020.
The device has a USB webcam that we are trying to pass into Citrix session. The issue is that when passed as HDX, the webcam is not recognized in Citrix session. When the device is passed in as generic USB the frame rate stays at unusable levels (1-4fps).
The configs in wnos.ini are:
SessionConfig=ALL VUSB_VIDEO=yes (for generic)
and
SessionConfig=ALL VUSB_VIDEO=no (for HDX)
The ThinOS Lite is ver 2.6. Windows machines don’t have the same issue.
Any suggestions on what can be done within device config to improve the performance?
Thanks!
As you are using an ARM based thin client, there is no option to use RTME.
Therefore, USB redirection is the only way to go.CG
I doubt that you can tweak anything in the config file. USB redirection is simply a lot slower than native redirection.

I have Webcams working in Citrix XenDesktop with the following WMS.ini config
SessionConfig=ica
ondesktop=desktops PasswordExpireNotify=yes HttpUserAgent=”” ClientName=”” AudioQuality=default DiskMapTo=”” DesktopMode=fullscreen SessionReliability=yes USBRedirection=hdx HDXFlashUseFlashRemoting=Always HDXFlashEnableServerSideContentFetching=Enabled EnableRTME=yes FlipByTimer=0SessionConfig=all

Our 3040 ThinOS clients connect using Citrix XenDesktop and work fine in something like Cisco WebEx but will not work with things like WebRTC such as being recognized in a Google Chrome of Firefox browser, its a limitation of the Citrix Receiver version that is modified for use in ThinOS.
So a couple questions to ask are:
- Is this XenApp or XenDesktop?
- What application are you trying to use the webcam with?
- Does the Webcam show you a video preview from the thin client directly?
You won’t see the webcam in Device’s and Printer as a Citrix HDX Webcam, it should appear as a video source option from whatever application you’re using unless its WebRTC based. Happy to help if i can. Slip gaji.
From our testing here there isn’t a workaround for ThinOS.
We also tested the following:
- A full Windows install of Citrix Workspace using Xendesktop to a Windows 10 VM works fine for apps and WebRTC only with VDA 1903 or 1904
- Linux Citrix Workspace using XenDesktop to a Windows 10 VM did not work, same error as ThinOS
- Apple Mac Citrix Workspace using XenDesktop to a Windows 10 VM did not work, same error as ThinOS
Seems to be a limitation of Citrix and WebRTC based connectivity for OS’s outside of Windows and VDA 1903/04
Great news!
our issue is with a specific app built off WebRTC and Citrix can’t hook into it.
it also may be worth trying my camera settings. We found this to perform better in HDX vs the default ThinOS settings with our Logitech C920’s

Is your ThinOS audio policy set for USB redirect or HDX?
So in my string you have:
- VUSB_AUDIO=yes – this is USB pass through, change to no for HDX
- VUSB_VIDEO=no – this is using HDX
Attached to my 3040 is a Logitech C920 camera, the camera comes through as Citrix HDX Webcam and my audio comes through as the Logitech C920. Do you have the drivers for the P2418HZ installed on whatever VDA endpoint you’re connecting to?
Since audio is doing USB pass through you may need to switch in Windows what is detected as the Default Recording Device. If you don’t see the p2418HZ listed in the default recording device list with USB pass through you may need to install the drivers for it, i’m not sure the default USB driver store in Windows has that driver for a built in mic on a monitor.
