It probably works as well. But I think the standard is like the following. http://git.kernel.org/?p=linux/hotplug/udev.git;a=blob;f=rules/rules.d/50-udev-default.rules;hb=HEAD 54 # 'libusb' device nodes 55 SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664" -- Xiaofan -- libftdi - see http://www.intra2net.com/en/developer/libftdi for details.
