| # 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). |
