Or, for per-device configuration, example USB ID 0483:df11:
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483",
ATTRS{idProduct}=="df11", MODE="664", GROUP="plugdev"
where the existing plugdev group is used (covers typical desktop users
on Debian/Ubuntu). I also filter for the "add" action, since this is
pointless on device removal.

No, rebooting is not necessary. The rules.d directory is usually
watched by udevd using inotify. In the worst case you must run "sudo
udevadm control --reload-rules".
