# 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 (libusb/hid.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/libusb SUBSYSTEM=="usb", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", MODE="0666" # If you are using the hidraw implementation (linux/hid.c), then do something # like the following, substituting the VID and PID with your device. Busnum 1 # is USB. # HIDAPI/hidraw KERNEL=="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).
