How to troubleshoot Webcams

Causes:

Webcam will not work if 

• the webcam that you are using does not support USB 1.1.
• the webcam is connected to a USB 2.0 port internal/external USB hub and will present you error "USB device not supported behind a high-speed hub" in attached devices on Zero Client.
• the USB Redirection on the host side is disabled, and the webcam will show as a "Not Supported" in attached devices.

Either Video or audio will not work if you have other USB devices using the OHCI mode to transfer data.
Isochronous USB devices (Webcam) are not supported with HP Anyware.
 

Resolution:

Note:

• At this stage, isochronous USB devices are not supported with HP Anyware. Please contact HP Anyware Sales for further information regarding this feature. Feature Requests and Accelerated Development (1437)
• Ideally, a functional webcam connected to Zero Client will show status Connected when in session and only webcam using OHCI controller and all other Attached devices using EHCI.

How To check the device status on the Zero Client:

• Log in to the Zero Client web interface. (To access the web interface, browse to the IP address of the zero client from a browser and log in.)
• Go to Info and then Attached device, this page should give you status of the USB devices attached to Zero Client.

Webcam will not show under attached devices in Zero Client.

• Connected Webcam do not support USB 1.1, make sure you are using a web cam that supports USB 1.1

Web cam shows status as "Not Supported" in attached device.

• USB Redirection needs to be enabled on the host side. If it is not enabled, USB Webcam status on Zero Client’s Attached Devices when in-session will say “Not Supported”. If successful, the webcam status will state ‘Connected’ or ’Remote’. More info about USB status in KB 1538.

Webcam shows status as "USB device not supported behind a high-speed hub"

• Zero Client supports webcams that supports USB 1.1. Isochronous USB 2.0 video devices connected through an internal/external USB hub are not supported and may see the following error message; USB device not supported behind a high-speed hub. Resolution is to plug the webcam to zero client's root USB port. KB 1221, How to identify root port?

Webcam is connected but either video or the audio do not work.

• User faces this issue when OHCI channel is used by other USB devices including the audio.  Some webcam will have inbuilt mic/ audio device and so the audio will also try using the OHCI channel and that can affect the video from webcam. Resolution to this issue is to use a headset and force audio from the headset rather than the webcam inbuilt audio system.
