96 96  If you are running KLOTS from a non-root user, you will need to ensure that you have read and write access for the NXT USB device in ///dev/bus/usb//. If you can identify the device in ///dev/bus/usb//, you can do this by:
97 97  
98 -{{code language="bash"}}
99 -sudo chmod a+w /dev/bus/usb/xxx/yyy

101 101  
102 102  However, the //yyy// number will count up each time the NXT is disconnected and reconnected. A better solution is to use **udev rules**. How to do this may vary with different Linux systems. To use //udev rules//, set up a file such as ///etc/udev/rules.d/70-lego.rules// and populate it with the following lines:
103 103  
104 -{{code language="bash"}}
105 -# Lego NXT
106 -BUS=="usb", SYSFS{idVendor}=="03eb", GROUP="a Linux user group", MODE="0660"
