Topic: Reading input from USB device

Anyone has experience with interfacing with USB devices? I managed to find my device, but it complains about unsufficient permissions, when I try to open it. The libusb wiki mentions udev as a solution, but I am a bit lost on how to piece things together here. Any pointers welcome.

There's some info here: https://wiki.archlinux.org/title/Udev -- section 4.2 deals with user permissions.

Though, a quick solution would be to access the device as root.
