Udev problems with leap 15.4/15.5 which works on 15.2

tkmbe · July 5, 2023, 8:53pm

Hello

I have a kingston cfreader and have the following udev rules in file /etc/udev/rules.d/97-kingston-cf-reader.rules

KERNEL=="sd*", ATTRS{serial}=="000004355", SYMLINK+="cfreader%n"

In leap 15.2 it creates the device reader with the first free device like

/dev/cfreader -> sdb
/dev/cfreader1 -> sdb1
/dev/cfreader2 -> sdb2

but since leap 15.4 default device without partition is different as partitions…

/dev/cfreader -> sdc
/dev/cfreader1 -> sdb1
/dev/cfreader2 -> sdb2

The right device are the partition in this example sdb.
and I cannot access the device with /dev/cfreader for example to install lilo
The serial is the correct one .

What could be the problem? Any ideas?

If you are sure that the drive is sdb, the you could cahnge the udev line to KERNEL==“sdb*” and see if that works.

Still if the udev rule now works for sdc it means that sdc somehow has the serial indicated…

Typically udev rules are based on the idVendor and idProduct tags what makes sense, you want it to work for all “kingston-cf-reader”-s not only the one with the give serial number. So another option is to update the udev rule to use idVendor and idProduct tags instead the kernel and serial. You can find those idVendor and idProduct using “lsusb -v”

It’s the same with the following rules:

KERNEL=="sd*", ATTRS{idVendor}=="11b0", ATTRS{idProduct}=="6108", SYMLINK+="cfreader%n"

Of course the device will not be always /dev/sdb that’s the problem.

tkmbe · July 7, 2023, 9:18pm

Difference of output from udevadm info -a -n /dev/sdb and udevadm info -a -n /dev/sdc
I still do not understand why it will mount /dev/cdreader i.e. whole “disk” to /dev/sdc
and partitions to /dev/sdbX

output of udevadm info -a -n sdbc

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

output of udevadm info -a -n sdb1

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

If dealing with a limited number of frequently used USB volumes, you may wish to consider including them in /etc/fstab/, along with specific mount options and locations. To facilitate this, give each volume a unique LABEL using tune2fs, e2label, or one of the FAT or other labeling tools after formatting, or as a command option when formatting, and configure mounting by their humanly memorable LABELs rather than immemorable UUIDs or inconsistent device names. The Leap I’m using to write here has 155 lines in /etc/fstab.

arvidjaar · July 8, 2023, 5:01am

ATTRS{serial} will search for the serial attribute on any parent of this device. In this case it is your USB multi-format reader (FCR-HS215/1). Each block device is child of this USB device and attempts to create the same links. The last block device for which this rule runs wins. It worked previously just by pure luck. You obviously cannot assign the same name cfreader1 to both sdb1 and sdc1

You need to use unique (base) name for each block device. %n is not enough because they overlap.

Did you look at existing /dev/disk/by-* links? udev already goes out of its way to give you persistent stable links.

arvidjaar · July 8, 2023, 7:01am

That is not how you post command output. Please, always copy and paste the full command line, its complete output and subsequent shell prompt, all as one chunk of text. Only then can we be sure that you actually run the command you described and its output is complete. And yes, it happens quite often that commands get entered wrong, like confusing capital and small letters, missing spaces etc.

tkmbe · July 12, 2023, 2:20pm

I don’t want to have /dev/sdb and /dev/sdc the udev mounter is doing that.
Of course it should be the same device so I don’t know which the partitions are right i.e. set to /dev/sdbX
and whole device is /dev/sdc instead of /dev/sdb!
I cannot to mounts with fstab etc. fixed because the amount ofpartition depends of the target system I use OpenSuse to install embedded systems and need to install lilo to the cfreader is all automated…

arvidjaar · July 12, 2023, 2:31pm

Your hardware cannot read your mind. Your multifunctional card reader provides (at least) two different block devices. Which is rather logical if you can use several slots at the same time - each slot has to be addressed as separate device.

Did you even try to look at /dev/disk/by-* links?

tkmbe · July 17, 2023, 4:09pm

I don’t understand why I have
usb-Kingston_FCR-HS219_1_114601005146-0:0 pointing to /dev/sdb
and it is not reflected to /dev/cfreader
while
usb-Kingston_FCR-HS219_1_114601005146-0:1 pointing to /dev/sdc
is reflected to /dev/cfreader
Why do I have 2 kingston readers :0 and :1?
This is the same problem with 2 differente models of kingston readers…

Because your reader has multiple slots and they can be used at the same time and each slot needs its own device. Hey, did not I already told you that?

tkmbe · July 25, 2023, 9:04pm

I know the reader has multiple slots but there are recognized as for example
/dev/sdb
/dev/sdc
/dev/sdd
/dev/sde
but the partition of /dev/sdb SHOULD be /dev/sdb1 /dev/sdb2 etc. of course and–

Now after upgrading a lot of packages suddenly it works right…

arvidjaar · July 26, 2023, 4:09am

Then write the correct udev rule that matches sdb1 to sdb, not to some random device of your multifunctional reader. Which is what I’m trying to tell you all the time but you are not listening.

karlmistelberger · July 26, 2023, 4:55am

To my experience udev works until users start tinkering. Temporarily rename the rules file and show the output of ls -1 /dev/disk/by-id/:
