1# This is a sample udev file for HIDAPI devices which changes the permissions 2# to 0666 (world readable/writable) for a specified device on Linux systems. 3 4 5# If you are using the libusb implementation of hidapi (libusb/hid.c), then 6# use something like the following line, substituting the VID and PID with 7# those of your device. Note that for kernels before 2.6.24, you will need 8# to substitute "usb" with "usb_device". It shouldn't hurt to use two lines 9# (one each way) for compatibility with older systems. 10 11# HIDAPI/libusb 12SUBSYSTEM=="usb", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", MODE="0666" 13 14 15# If you are using the hidraw implementation (linux/hid.c), then do something 16# like the following, substituting the VID and PID with your device. Busnum 1 17# is USB. 18 19# HIDAPI/hidraw 20KERNEL=="hidraw*", ATTRS{busnum}=="1", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", MODE="0666" 21 22# Once done, optionally rename this file for your device, and drop it into 23# /etc/udev/rules.d and unplug and re-plug your device. This is all that is 24# necessary to see the new permissions. Udev does not have to be restarted. 25 26# Note that the hexadecimal values for VID and PID are case sensitive and 27# must be lower case. 28 29# If you think permissions of 0666 are too loose, then see: 30# http://reactivated.net/writing_udev_rules.html for more information on finer 31# grained permission setting. For example, it might be sufficient to just 32# set the group or user owner for specific devices (for example the plugdev 33# group on some systems). 34
