# This is a sample udev file for HIDAPI devices which lets unprivileged
|
|
# users who are physically present at the system (not remote users) access
|
|
# HID devices.
|
|
|
|
# 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.
|
|
|
|
# HIDAPI/libusb
|
|
SUBSYSTEMS=="usb", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", TAG+="uaccess"
|
|
|
|
# If you are using the hidraw implementation (linux/hid.c), then do something
|
|
# like the following, substituting the VID and PID with your device.
|
|
|
|
# HIDAPI/hidraw
|
|
KERNEL=="hidraw*", ATTRS{idVendor}=="04d8", ATTRS{idProduct}=="003f", TAG+="uaccess"
|
|
|
|
# Once done, optionally rename this file for your application, and drop it into
|
|
# /etc/udev/rules.d/.
|
|
# NOTE: these rules must have priority before 73-seat-late.rules.
|
|
# (Small discussion/explanation in systemd repo:
|
|
# https://github.com/systemd/systemd/issues/4288#issuecomment-348166161)
|
|
# for example, name the file /etc/udev/rules.d/70-my-application-hid.rules.
|
|
# Then, replug your device or run:
|
|
# sudo udevadm control --reload-rules && sudo udevadm trigger
|
|
|
|
# Note that the hexadecimal values for VID and PID are case sensitive and
|
|
# must be lower case.
|
|
|
|
# TAG+="uaccess" only gives permission to physically present users, which
|
|
# is appropriate in most scenarios. If you require access to the device
|
|
# from a remote session (e.g. over SSH), add
|
|
# GROUP="plugdev", MODE="660"
|
|
# to the end of the udev rule lines, add your user to the plugdev group with:
|
|
# usermod -aG plugdev USERNAME
|
|
# then log out and log back in (or restart the system).
