please check if its visible when you run

lsusb

it is likely a USB connection problem, not a libgphoto2 problem.

Thanks for the reply. Yeah, it doesn't show in lsusb. What can I do to fix it? Other devices work fine on all of the USB ports. If i turn off the camera it can charge through the USB port.

I had similar issues with my Nikon Z30 at the beginning, connected to a Raspberry Pi does not work probably caused by low voltage via USB. After I set "Menu > Setup Menu > USB power delivery" to OFF it works fine.
