3# Suggested udev rules to be able to access the Logic device without being root:
4# SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="0925", ATTR{idProduct}=="3881", MODE="0666"
5# SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ATTR{idVendor}=="21a9", ATTR{idProduct}=="1001", MODE="0666"
