OK, followup. I removed the write-protect detection from usb-storage, and now the cardreader seems to be detected correctly - however now I get the same error as I did with earlier kernels:
Code:

SCSI device sdc: 512000 512-byte hdwr sectors (262 MB)
sdc: assuming Write Enabled
sdc: assuming drive cache: write through
SCSI device sdc: 512000 512-byte hdwr sectors (262 MB)
sdc: assuming Write Enabled
sdc: assuming drive cache: write through
 sdc: unknown partition table


touch /dev/sdc does not create /dev/sdc1. Neither does udevstart...

Edit: If I rmmod -f usb_storage, and insert an mmc card and wait awhile until I modprobe usb-storage again udev creates the correct device for the card. Go figure...

Is it safe to change udev rules so that it uses no devfs style names at all?

The last postings was with the 2.6.10-r4 gentoo-dev-kernel. Also 2.6.9-r9 and -r13 does not work.

Thanks for your howto. You write there that udev depends on sysfsutils. I cannot confirm this, when I emerged udev it wasn't installed and there seems to be no dependency. Is sysfsutils really needed?

Thanks for the notification, I wasn't aware of the change in deps.

Later: Updated UDEV Primer, with the sysfsutils information.

I am not a Gentoo Dev, so if someone finds out information like this, feel free to notify me. Otherwise, I usually don't hear about it until there is a complaint or someone has a problem. Thanks.

I posted this in another thread but got no response, and this looks like a better place for it anyhow.

Now that I'm running a 100% udev system I'm unable to access a 1680 KB formatted floppy. When I had devfs there was a device node called fdu1680 which allowed me to mount it like so:

Code:
mount -t msdos /dev/fdu1680 /mnt/floppy


Under udev the fdu1680 device is not automatically created. What is the proper way to get udev to do so? Simply adding a symlink in the "fd" entry in /etc/udev/rules.d/50-udev.rules doesn't work because the created node doesn't get assigned a minor number of 44 like it needs. What am I missing?

Don't have much time to look at this, but you could create it in local.start like we did before for the nvidia devices.
Then file a bug report so Greg will see it.
Cause looks like a device that might have not been added to udev yet. At least I have never seen it.

I'll give that a shot.

By the way, you'll find many devices that may not be in udev listed here:

http://www.bb-zone.com/SLGFG/chapterA.html

The one I'm needing is listed in Table A-6.

Sorry I'm out of it today. Where I wrote "fdu1680", please substitute that with "fd0u1680". :oops:

My problem remains the same however.

I really need help with udev. I've been reading and searching the forums, but haven't found the answers yet.

I followed the user docs: http://www.gentoo.org/doc/en/migration-to-2.6.xml and http://www.gentoo.org/doc/en/udev-guide.xml, but have two problems.

I emerged udev, hotplug and coldplug as instructed.

Relevent sections of my kernel (2.6.10-gentoo-r5) config:
Code:
#
# Pseudo filesystems
#
CONFIG_PROC_FS=y
CONFIG_PROC_KCORE=y
CONFIG_SYSFS=y
# CONFIG_DEVFS_FS is not set
# CONFIG_DEVPTS_FS_XATTR is not set
CONFIG_TMPFS=y
# CONFIG_TMPFS_XATTR is not set
# CONFIG_HUGETLBFS is not set
# CONFIG_HUGETLB_PAGE is not set
CONFIG_RAMFS=y

Code:
#
# General setup
#
CONFIG_LOCALVERSION=""
CONFIG_SWAP=y
CONFIG_SYSVIPC=y
# CONFIG_POSIX_MQUEUE is not set
CONFIG_BSD_PROCESS_ACCT=y
# CONFIG_BSD_PROCESS_ACCT_V3 is not set
CONFIG_SYSCTL=y
# CONFIG_AUDIT is not set
CONFIG_LOG_BUF_SHIFT=14
CONFIG_HOTPLUG=y
CONFIG_KOBJECT_UEVENT=y
# CONFIG_IKCONFIG is not set
# CONFIG_EMBEDDED is not set
CONFIG_KALLSYMS=y
# CONFIG_KALLSYMS_EXTRA_PASS is not set
CONFIG_FUTEX=y
CONFIG_EPOLL=y
# CONFIG_CC_OPTIMIZE_FOR_SIZE is not set
CONFIG_SHMEM=y
CONFIG_CC_ALIGN_FUNCTIONS=0
CONFIG_CC_ALIGN_LABELS=0
CONFIG_CC_ALIGN_LOOPS=0
CONFIG_CC_ALIGN_JUMPS=0
# CONFIG_TINY_SHMEM is not set


1) ps -A shows that devfsd is still running and the console shows it being started on boot:
Code:
# ps -A
  PID TTY          TIME CMD
     121 ?        00:00:00 devfsd

According to the udev-guide "The Gentoo init scripts won't run the devfsd daemon and will deactivate devfs when you boot up."

Why is it still being started? How do I prevent it from being started?

2) The printer stopped working. It was directed at URI: parallel:/dev/printers/0. This device no longer exists.
Code:
# ls -al /dev/printers
ls: /dev/printers: No such file or directory
According to the udev-guide "Gentoo will use udev but keep a static /dev so that you will never have any missing device nodes. "

Since I will never have any missing device nodes and /dev/printers/0 is missing, what device should CUPS be set to for my parallel printer?

Thanks in advance!

Darrell


Update:
Solved this by:
emerge -e system,
fix_libtool_files.sh 3.3.4,
revdep-rebuild,
libperl_rebuilder,
and upgrading from gentoo-dev-sources-2.6.10-r5 to 2.6.-10-r6.

Something was corupted and this seems to have fixed it.

PostPosted: Fri Jan 21, 2005 10:27 pm    Post subject: migrating from devfsd -> udev Reply with quote

I have followed a number of the discussions.

I recompiled kernel per suggestions with most already taken care of and did an emerge on udev.

Though I have a /sys I'm seeing nothing in it. Should I?

I might add that I do see a typical scsi sort of listing in /dev/ide/host0/
It leads to listing for my primary and secondary controllers. Also I have what I assume is the old listing or perhaps that is the udev listing hd with cd being the secondary controller.

I also have a /proc/sys filled with info, but I suspect I need do more.

Any input is appreciated.

if you arent careful you could avoid compiling sysfs support into your kernel

you could try mounting it with
mount -t sysfs none /sys

and checking that sysfs is listed in /proc/filesystems

PostPosted: Sun Jan 23, 2005 9:43 am    Post subject: 2.4 kernel and udev Reply with quote

I do not see it mentioned, but though it appears 2.6 comes with sysfs and necessary utilities 2.4 does not. I ahve looked at the kernel migration doc and my intent, for now, is to simply retain the 2.4.26 kernel, but switch to the udev system.

This leads to my question. The udev I have currently installed does not supply all necessary utilities, I believe. sysfsutils would seem to be necessary to fully implement udev on a 2.4 system. Would someone confirm or elaborate on this question for me?

Yes, I realize I could simply fully upgrade to 2.6, but this is my first Gentoo install and I am anxious to continue building it. I have another set of partitions that I will wipe, currently, SuSE 9.0, and never very fully functional, which is quite a contrast to my first step into Gentoo.

Thanks.

udev requires sysfs. sysfs is present in linux 2.6 and not on linux 2.4

if you are still using 2.4 then you cannot use udev.

i've been noticing a lot of instability in udev (or at least gentoo's udev configuration). when ever i upgrade my udev, i seem to have local rules that no longer work. today, i'm trying to mount my digital camera. i had a rule setup to create a symlink to /dev/camera (from /etc/udev/rules.d/10-custom-udev.rules):
Code:

BUS="usb", SYSFS{idVendor}="04cb", SYSFS{idProduct}="0126", NAME="%k", SYMLINK="camera"


i got those id's from using
Code:

udevinfo -a -p /sys/block/sda/


Code:

  looking at the device chain at '/sys/devices/pci0000:00/0000:00:10.1/usb2/2-1':
    BUS="usb"
    ID="2-1"

any ideas would be most appreciated. i'm currently on udev 052, and i don't recall what i upgraded from or when my camera worked last, i don't use it every day or every upgrade for that matter.

thanks!

Remerge udev-050 and see if you still have the problem. I find myself keep going back to that version.
The newer ones keep screwing with my flashdisk and no devices is created.

actually, i had to take it back to 045. 050 didn't seem to work either, so i removed the sys-fs/udev from the /etc/portage/package.keywords. now the camera shows up fine. udev must be very very dependant on other systems/packages. and perhaps, very dependant on specific versions of those other packages.

frustrating.

hi all,
i have two problems:

1) automount for my mega external HD doesn't work

Code:

omega root # ls -aFl /etc/dev.d/maxtor1/automount.dev
4,0K -rwxr-xr-x  1 root root 219 14 mag 16:33 /etc/dev.d/maxtor1/automount.dev*
omega root # cat /etc/dev.d/maxtor1/automount.dev
#!/bin/bash
if [ "$ACTION" == "add" ] ; then
 logger -t dev.d "Mounting external HD"
 /bin/mount /mnt/maxtor
fi
if [ "$ACTION" == "remove" ] ; then
 logger -t dev.d "Unmounting external HD"
 /bin/umount /mnt/maxtor
fi
omega root #


2) i have an mp3 reader that have incorporated a flash memory storage, but it is also an SD/MMC writer/reader.
what is the rule for mounting flash memory and my SD both?
they have same "vendor", "model", or "serial"

rules that i have tryed are:

BUS="scsi",SYSFS{vendor}="Digital",SYSFS{model}="MP3 Music Player",KERNEL="sd*",NAME="%k",SYMLINK="magnex%n"


but that are the results

Code:

omega root # udevstart
omega root # ls /dev/ma* -Afl
lrwxrwxrwx  1 root root 3 15 mag 16:16 /dev/magnex -> sdc
lrwxrwxrwx  1 root root 4 15 mag 16:16 /dev/magnex1 -> sdc1
lrwxrwxrwx  1 root root 3 15 mag 16:16 /dev/maxtor -> sda
lrwxrwxrwx  1 root root 4 15 mag 16:16 /dev/maxtor1 -> sda1



thank you for helping

First of all, thanks for your time and for helping me out.

I have problems with udev, too. In my case, I'm trying to configure autodetection and automounting for a Sony USB 2.0 flash disk incorporating a Memory Stick reader.

This is what I get from lsusb:
Code:

This is the info from "dmesg":

The following two commands demonstrate the system is aware of its presence once plugged in.
Before:
Code:
# ls /dev/sd* -Afl
ls: /dev/sd*: No existe el fichero o el directorio
#

After:
Code:
 ls /dev/sd* -Afl
brw-rw----  1 root disk 8,  0 nov 16 17:19 /dev/sda
brw-rw----  1 root disk 8, 16 nov 16 17:19 /dev/sdb
#


On the other hand, my system does _NOT_ show the message
Code:
mounting ramfs at /dev
at boot time. What can I try to solve this issue? Is this related to udev not working properly?
Also, where is the system boot log, so that I can take a closer look at it and post the relevant part here?

if sda is appearing after plugin then udev is doing its job just fine. have you tried mounting it?

Thanks for your help. Yes. I used to have an entry in /etc/fstab for that purpose, and an icon in my KDE desktop. Double-clicking the icon would mount the flash disk.
However, I'm trying to get the system to automatically detect when the flash disk is inserted AND place the corresponding icon on the desktop. To achieve that, I followed the HOWTO in this thread: HOWTO Fully Automated USB mounting using udev [WIP], yet to no avail.

I think the problem might be that I don't see (get?) /dev mounted on ramfs at boot. At least, that is what is explained at the end of point 5 in this page: UDEV Primer
Quote:
Now at this point you might think you actually have udev, sysfs and hotplug installed and ready to go. Sorry, but NO. Until sysfs is mounted, /dev mounted in ramfs and hotplug started you aren't really doing anything. You will see changes in /sys if remove or add devices, but the system is not doing anything with this information.


Is that the reason for my failure, or is it something else?
And, is there an easier and working method to achieve what I want using udev?

i think you are reading into that too much - if nodes are being created on plugin in /dev then your udev is definately working/
you can find out which filesystem /dev is on by running "mount".

mine says:
Code:
udev on /dev type tmpfs (rw,nosuid)


so mine isnt on ramfs either... and it works just fine :)
