I have been reading about webcams, etc. and Linux and am working with my LePotato running Ubuntu 22.04. I added the Arduino CSI-USB converter so I can plug in an RPiHQ cam into the USB port. I see the following in the log messages:
pi@lepotato:~$ dmesg | grep Camera
[    4.431905] usb 1-1.2: Product: Arducam IMX477 HQ Camera
[    8.798501] uvcvideo: Found UVC 1.00 device Arducam IMX477 HQ Camera (0c45:636d)
[    8.806595] input: Arducam IMX477 HQ Camera: Arduc as /devices/platform/soc/d0078080.usb/c9000000.usb/xhci-hcd.2.auto/usb1/1-1/1-1.2/1-1.2:1.0/input/input3

 

But I have no idea how to test further.

 

I've tried cheese:
 

cheese

** (cheese:4159): ERROR **: 13:06:46.007: cheese-application.vala:89: Unable to initialize libcheese-gtk
Trace/breakpoint trap (core dumped)

 

cheese -d [total guess at device] 

same as above

 

And libcam-hello:

libcam-hello
-bash: libcam-hello: command not found

 

I've tried installing libcam following what I found Googling, but I just keep digging a deeper hole.

 

I am lost. The camera works fine with Raspbian Bullseye in CSI mode, but my limited knowledge doesn't tell me whether the messages I'm seeing with Armbian mean much. What should I do next?

Thanks.

 

 

uvc cameras can be used with guvcviewer and mjpegstreamer
