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