In the case a user have the read right on the node without the write right, this patch would allow the normal use of my usbdevs-like tools for this user. In a system with default permission, this won't change anything as root and wheel have read + write permission on /dev/usb nodes and everybody else have nothing. -- Cordialement, Coues Ludovic +336 148 743 42
