Linux

USB-HID devices in Linux are by default owned by the root user, so running the script with sudo would be required. To run as normal user, you'd need to create a udev rule.

This is a file you create in /etc/udev/rules.d/, e.g. /etc/udev/rules.d/100-big-red-button.rules, with the following contents:

ATTRS{product}=="DL100B Dream Cheeky Generic Controller", MODE:="666"

Then, run

$ sudo udevadm control --reload-rules

and unplug and re-plug the device to apply the new rule. If it still does not work, you may need to adapt the attribute to match what your device is sending.
