udev: symlink for my meizu m6

eantoranz · 01-03-2008, 11:13 AM

I want to create a symlink to my meizu m6.... say something like /dev/meizu
How do I specify a rule for udev to do it?

Here's the info for the device:

Code:

$ udevinfo --query=all --name=sdb
P: /block/sdb
N: sdb
S: disk/by-id/usb-Meizu_MiniPlayer_000000E5E5000-0:0

There may already be a file in /etc/udev/rules.d that contains a rule for your device and if so, you can edit it to suit your needs. Let's assume there isn't such a file. You can make a rule like this:

ENV{ID_VENDOR}=="Meizu", ENV{ID_MODEL}=="MiniPlayer", ENV{ID_SERIAL_SHORT}=="000000E5E5000", SYMLINK+="meizu"

Add this as a single line to a new file in /etc/udev/rules.d, which you can call something like 10-local.rules. I've deliberately chosen properties that are meaningful (model, manufacturer, serial number) because it makes more sense to identify a device by those things rather than, say, file system type.

eantoranz · 01-03-2008, 11:36 AM

Ok... let my try that. I wonder if it's possible to use ID_FS_UUID to identify it.

Code:

ENV{ID_FS_UUID}=="68DE-5DE7",SYMLINK+="meizu"

Nylex · 01-03-2008, 11:51 AM

Of course you're free to add that property to the rule!

eantoranz · 01-03-2008, 11:55 AM

Good to know, however, it didn't work your way... nor mine. :-)

I don't have to restart udev (/etc/init.d/udev restart) after adding/editing the file, right? Cause I just read that files are read by udev when events are performed by the kernel.

Here's the file as I created it:

Code:

$ cat 62-meizu.rules
# Reglas para el meizu m6
#ENV{ID_VENDOR}=="Meizu", ENV{ID_MODEL}=="MiniPlayer", ENV{ID_SERIAL_SHORT}=="000000E5E5000", SYMLINK+="meizu"
ENV{ID_FS_UUID}=="68DE-5DE7", SYMLINK+="meizu"

I tried with the first line first. It failed, so I commented it and tried with the second (mine). Didn't work either.

By the way, I'm on kubuntu gutsy.

Nylex · 01-03-2008, 11:59 AM

Yeah, you shouldn't need to restart udev but it wouldn't hurt to do so. Just to check: are there any other files in /etc/udev/rules.d?

eantoranz · 01-03-2008, 12:05 PM

Yes, there are a number of files.

Code:

And README says:

Code:

$ cat README
The files in this directory are read by udev(7) and used when events
are performed by the kernel.  The udev daemon watches this directory
with inotify so that changes to these files are automatically picked
up, for this reason they must be files and not symlinks to another
location as in the case in Debian.

Files should be named xx-descriptive-name.rules, the xx should be
chosen first according to the following sequence points:

  00   rules that it is critical to be run first, usually
       only WAIT_FOR_SYSFS

  20   rules that change the name from the device from the default
       (cannot be overriden)

  40   rules that set the permissions of device nodes
       (can be overriden by later rules)

  60   rules that add symlinks to device nodes
       (adds to those set in earlier rules)

  80   rules that run programs (but do not load modules)

  90   rules that load modules

  99   rules that it is critical to be run last


This scheme has been chosen so that user-supplied rules are normally
named 50-*.rules for the right thing to happen.

Packages should chose the approriate sequence point and add 5 to it
(e.g. 25-iftab.rules, 45-libsane.rules, etc.) unless there is a need
for a particular order.

That's why I numbered my file 62. I didn't change any other file.

Nylex · 01-03-2008, 12:09 PM

Ok. In theory it should work then. First try restarting udev and see if you have a /dev/meizu. I've had strange problems with udev rules that seem to fix themselves after a restart of the udev daemon. Edit: also, let's see what's in your 60-symlinks.rules and 65-libmtp.rules files (I'm not sure if your device uses MTP or not).

eantoranz · 01-03-2008, 12:24 PM

Is it possible to see what rules are being applied on a device? Maybe with udevmonitor?

Nylex · 01-03-2008, 12:29 PM

I've never actually used udevmonitor (apart from just now), but it's worth a try to see what's happening. Try running it with the --environment option and see what that gives you. For example, running it after turning my USB DVD-rewriter on gives me (amongst other things)

DEVLINKS=/dev/disk/by-id/usb-ATAPI_DVD_A_DH20A3P_0000000000121C73-0:0 /dev/disk/by-path/pci-0000:00:1d.7-usb-0:2:1.0-scsi-0:0:0:0 /dev/cdrom /dev/dvd /dev/dvdrw /dev/cdrw,

which shows the symlinks my udev rules have created.

eantoranz · 01-03-2008, 12:30 PM

It can use MTP or MSC. Right now it's MSC.

Anyway, here are the files:

60-symlinks.rules

Code:

# This file establishes user-friendly symlinks to devices according to
# Ubuntu policy.  See udev(7) for syntax.
#
# The names of the actual devices themselves must not be set here, but
# in 20-names.rules; the permissions and ownership of those devices
# should be set in 40-permissions.rules.

# Compatibility symlinks for /dev/scd* devices

                                        SYMLINK+="pilot"

There's nothing in those files specifically referring to your device. Another thing you could try is making your rule similar to the ones in those files (i.e. using ATTRS{*} and SYSFS{*} keys rather than ENV{*} ones). To see what's relevant, use "udevinfo -a -p /sys/block/sdb".

Now we're talking!

Let me see what I can do from that command output.

eantoranz · 01-03-2008, 01:20 PM

It worked, man!

Code:

SUBSYSTEMS=="usb", DRIVERS=="usb", ATTRS{idVendor}=="0492", ATTRS{idProduct}=="0140", ATTRS{serial}=="000000E5E5000", \
        SYMLINK+="meizu"
