patch for udev rules
|
udev does not create nodes in /dev/bus/usb with the same permissions that were previously found in /proc/bus/usb. The permissions in /proc/bus/usb are provided by this mount rule: usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=0664,devgid=85) # find /proc/bus/usb /dev/bus/usb ! -type d -ls 5530 0 -rw-rw-r-- 1 root usb 43 Sep 22 21:09 /proc/bus/usb/003/001 13120873 0 -rw-rw-r-- 1 root usb 50 Oct 7 16:26 /proc/bus/usb/002/002 4501 0 -rw-rw-r-- 1 root usb 43 Sep 22 21:09 /proc/bus/usb/002/001 6533 0 -rw-rw-r-- 1 root usb 77 Sep 22 21:09 /proc/bus/usb/001/007 6394 0 -rw-rw-r-- 1 root usb 77 Sep 22 21:09 /proc/bus/usb/001/006 5894 0 -rw-rw-r-- 1 root usb 43 Sep 22 21:09 /proc/bus/usb/001/005 4397 0 -rw-rw-r-- 1 root usb 43 Sep 22 21:09 /proc/bus/usb/001/001 4263 0 -r--r--r-- 1 root root 0 Oct 7 16:26 /proc/bus/usb/devices 6492 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/003/001 6925 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/001/007 6899 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/001/005 6855 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/001/002 6853 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/001/001 6718 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/001/006 6165 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/001/003 6086 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/001/004 5517 0 crw-r--r-- 1 root root Sep 22 21:09 /dev/bus/usb/002/001 whereas udev has the following rule that does the incorrect thing: SUBSYSTEM=="usb_device", PROGRAM="/bin/sh -c 'K=%k; K=$${K#usbdev}; printf bus/usb/%%03i/%%03i $${K%%%%.*} $${K#*.}'", NAME="%c", MODE="0644" Find attached a patch against udev to resolve this.
