Udevinfo 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

OK I am confused on which BUS i should use sinbce there are at least 2 listed in this here is everything that udevinfo -a -p /sys/block/sde supplied me.

"Writing udev rules" says you should use things in your rule that come from the same section only. So, for example, you could use

BUS=="scsi", DRIVER=="sd", SYSFS{model}=="5000AAKS Externa", SYSFS{vendor}=="WD "

in your rule, taking stuff from the second section of your output from udevinfo. Edit: obviously this isn't a complete rule as there's no NAME or SYMLINK in it.

sulvereagle59 · 06-08-2007, 06:31 AM

OK, after writing the rule (with KWrite) an placing it in it's proper folder how do I find out if it worked or not? where do I look to see if it did?

Nylex · 06-08-2007, 06:37 AM

What did you use for NAME and/or SYMLINK in your rule? Check if there's a node in /dev with that name. You can do this with ls, e.g. if you named the device "usbdisk", run "ls /dev/usbdisk" and see if there's anything there.

sulvereagle59 · 06-08-2007, 06:58 AM

OK, this is exactly what I have for the rule

Quote:

BUS=="scsi", DRIVER=="sd", SYSFS{model}=="5000AAKS Externa", SYSFS{vendor}=="WD ", NAME="mybook", SYMLINK+="usbhd%n"

but it did not seem to work since when I out in

Quote:

ls /dev/mybook

I get the following message

Quote:

/bin/ls: /dev/mybook: No such file or directory

So what is it that I have done wrong?

Nylex · 06-08-2007, 07:01 AM

Try disconnecting the device (unmount it before doing so, if it's mounted) and reconnecting it and then trying again. Sometimes I have this with udev when adding a new rule.

sulvereagle59 · 06-08-2007, 07:11 AM

Nothing

Now should I try taking davids.rules out of the folder 10-local.rules and placing it in the folder rules.d??

Nylex · 06-08-2007, 08:57 AM

Yes. Try renaming the file to 10-local.rules as well. Edit: also see the "Debugging your rules" section in "writing udev rules".

sulvereagle59 · 06-08-2007, 11:21 AM

OK, I ran a udevtest and this was the results maybe it can help in determining what is happening. Only thing is I have no idea of what to look for to fix anything.Here is what the results from the test give

Looking at that output, it does appear that your rules aren't being applied. When you wrote the rule, you didn't split it on to two lines did you?

sulvereagle59 · 06-08-2007, 12:41 PM

OK after some playing around I have finally gotten the rule to work and also wrote a couple more and they are working

Here is what i did

Quote:

BUS=="usb", KERNEL=="sd*", SYSFS{product}=="External HDD", NAME="mybook", SYMLINK+="usbhd%n" (this for my HD)

BUS=="usb", KERNEL=="sd*", SYSFS{product}=="Cruzer Micro", NAME="flashdrive", SYMLINK+="usb-storage" (this is for one of my flashdrives)

BUS=="usb", KERNEL=="sd*", SYSFS{product}=="Flash Disk", NAME="flashdrive", SYMLINK+="usb-storage" (this for my other flashdrive

Now the question is what do I have to add to my /etc/fstab so that they depending on what I have loaded I can easily mount to be able to use?

Nylex · 06-08-2007, 01:06 PM

Are you sure you're a newbie?

In your fstab, you can now just use the symlinks as the device name in the first column and everything else as before. So, for your external hard disk, you used to have an entry like this:

/dev/sda2 /E vfat noauto,user,rw,exec,sync 0 0

You can now change the "/dev/sda2" to "/dev/usbhd2". The partition numbers are the same as before. I think you needed to mount /dev/sda5 to get it to work, right? So you'd actually use /dev/usbhd5. Does that make sense?

Similarly, just add an entry for your flash drives using /dev/usb-storage in the first column.
Here are my two entries

/dev/flash /mnt/memory vfat noauto,users 0 0
/dev/music /mnt/music vfat noauto,users 0 0

One's for my flash drive and the other is for my digital audio player.

Like you, I've got two flash drives and my udev rules are set up to call them both "flash". I don't know what would happen if I tried plugging them both in at the same time. I think maybe you'd have to use different names, rather than "usb-storage" for both.

sulvereagle59 · 06-08-2007, 01:54 PM

Thank you so much for your help. I have now got all my drives loaded and configured in fstab and are working great.

Nylex · 06-08-2007, 01:55 PM

Yay, good to hear
