Hi @michaelbusfield. Please provide more details about exactly what you were doing when you encountered this problem.

Did it occur when running an Arduino App Lab "App"? If so, is it one of the example Apps that come preinstalled in Arduino App Lab, or is it an App you created yourself.

Please provide details about the camera. Is this a webcam connected to the board via a USB-C hub?

Hi! Not sure if it's the same issue, but I'm having problems to make it work the face detection example. I've connected Uno Q via a USB-C hub. Camera and Arduino Uno Q are both connected in the same hub. I've tried to run the app from example face detection both in network mode or connecting the Arduino App lab through USB, but I got no camera found when running tha App. I've tested that Arduino Uno Q works for other examples where the camera is not needed and also my cam seems to work, because I'm able to use it in my Mac. Did you manage to solve the issue? any idea what could be wrong?
Thanks!

I'm connecting to the Arduino using Arduino App Lab via network and when running the App from the example I got missing required device: no camera found

Thanks for your help!

Hi @aliescont. The connections are incorrect. The USB-C plug on the hub must be connected to the socket on the UNO Q board. You currently have that plug connected to the power supply.

The power supply must be connected to the "PD" socket on the hub:

Correct the connections and then try again. Hopefully everything will work as expected now.

When you have a USB peripheral connected to the UNO Q board, it is not possible to use the board in the "hosted mode" where you run Arduino App Lab on your PC and connect it to the board via the USB connection. The reason is that the UNO Q is acting as a USB host in this case, not as a USB device as is the case when using the board in "hosted mode".

Thanks! I changed the USB hub and checked the connections and now it's working.
