Public bug reported:
Binary package hint: udev
I have two USB DVB-T TV tuners.
Both have IR receivers.
udev gives them the same path id:
malc...@mythtv:~$ /lib/udev/path_id
/devices/pci0000:00/0000:00:04.1/usb1/1-4/input/input8
ID_PATH=pci-0000:00:04.1
malc...@mythtv:~$ /lib/udev/path_id
/devices/pci0000:00/0000:00:04.1/usb1/1-1/input/input7
ID_PATH=pci-0000:00:04.1
I've applied the patch in bug 546128 to get by-path symlinks for input
devices, but there is only a symlink for one of them:
~$ ls -l /dev/input/by-path/
total 0
lrwxrwxrwx 1 root root 9 2010-07-15 17:48
pci-0000:00:04.0-usb-0:5:1.0-event-kbd -> ../event3
lrwxrwxrwx 1 root root 9 2010-07-15 17:48
pci-0000:00:04.0-usb-0:5:1.1-event-mouse -> ../event4
lrwxrwxrwx 1 root root 9 2010-07-15 17:48 pci-0000:00:04.0-usb-0:5:1.1-mouse ->
../mouse1
lrwxrwxrwx 1 root root 9 2010-07-15 17:48 pci-0000:00:04.1-event-ir -> ../event8
lrwxrwxrwx 1 root root 9 2010-07-15 17:48 pci-0000:00:04.1-usb-0:2:1.0-event ->
../event5
I expect path_id to return a unique identifier.
