Cisco Room USB (mini) : camera stops working in MS Teams call

[arjan.de.goede]

Hi,

We have several small meeting rooms with Cisco Room USB systems.  The user connects the HDMI and USB cables to the laptop and starts the meeting. Now recently on many laptops the camera stops working in a MS Teams call, using the camera of the Room Kit.

What can this be? When using webex with the same room USB system, the camera keeps working.

In Teams the message is: the camera is not responding or stops working or something like that and the user has to select the laptop camera. Before the meeting the camera is still working (when go into the Teams devices screen), bus as soon as the meeting is started, the camera stops working sooner or later....

I doubt this is your issue, but why are you connecting HDMI and USB-C between the devices? You should not need HDMI - your laptop (if it's a modern one) can use the USB-C for both the AV in from the Room USB and for AV out to display on the monitor connected to the Room USB. I have a desk Mini - same setup really, and my laptop is only connected to the device with one cable, not two. Again, maybe not your problem, but give it a try, perhaps your redundant connections are causing your issue.

As @PJMack suggested, connecting the HDMI cable is likely unnecessary and could be the cause of your issue.   You should only need to connect the Room device to the laptop with the USB-C cable.

Does the Room Kit mini (usb) support video over USB-C then ? the Room kit mini has an HDMI port to connect a monitor and an HDMI input port for the computer. The instruction on the screen says also: connect both USB and HDMI cables to the computer for a video call.
