 Posted: Fri May 13, 2005 6:28 pm Post subject: Udev not creating the correct devices [SOLVED] |
 |
|
I have udev set up on a per request basis so that cameras, usb sticks, etc are all created as /dev/fuji_cam, /dev/usb_stick, etc instead of /dev/sdx. It was all working fine until I updated the kernel from 2.6.11-r6 to 2.6.11-r8 and updated udev from 045 to 056. Now when I plug in devices I see this in dmesg:
| Code: |
usb 1-1: new high speed USB device using ehci_hcd and address 2
scsi0 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
Vendor: GENERIC Model: USB Mass Storage Rev: 1.00
Type: Direct-Access ANSI SCSI revision: 02
SCSI device sda: 1024000 512-byte hdwr sectors (524 MB)
sda: assuming Write Enabled
sda: assuming drive cache: write through
SCSI device sda: 1024000 512-byte hdwr sectors (524 MB)
sda: assuming Write Enabled
sda: assuming drive cache: write through
sda: sda1
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 0
usb-storage: device scan complete
bash-2.05b$

I have a rules script in /etc/udev/rules.d as:
| Code: |
(/etc/udev/rules.d/80-ipod.rules)
BUS="scsi", SYSFS{vendor}="Apple ", NAME="ipod%n", SYMLINK="ipod"
BUS="scsi", SYSFS{vendor}="FUJIFILM", KERNEL="sd?1", NAME="%k", SYMLINK="fuji_cam"
BUS="scsi", SYSFS{vendor}="Philips ", KERNEL="sd?1", NAME="%k", SYMLINK="usb_key"
BUS="scsi", SYSFS{model}="USB Mass Storage", KERNEL="sd?1", NAME="%k", SYMLINK="usb_stick"
|
After plugging in the USB stick there is no /dev/usb_stick directory - from dmesg it looks as though it is still being created as sda1.
Again, this worked fine until I synced and updated the kernel and udev last night.
I'm completely stuck with this now, any help would be greatly appreciated.
Thanks,

Change BUS="scsi" to BUS="usb" and try again.

I have a similar setup with that difference that my own rules are located in the file 10-udev.rules. The expected symlinks in /dev are still created but I don't see anyting which relates to that in the log files. They just show that sda and sda1 are created.
When I rename the file to 60-udev.rules (any name which is lexically larger than 50-udev.rules), I recreate your problem: the symlink is not created. Renaming it back to its original name solves the problem. So I suggest you rename your rules file to 30-ipod.rules.

Thanks, I renamed it to 10-blah.rules and it works again. Strange how its worked all this time when the file was 80-blah.
Anyway, thanks for the help

you're welcome,
During the etc-update after udev056 was emerged, I noticed some serious changes in 50-udev.rules - just did the emerge half an hour before I saw your post. My guess is that these changed/added default rules somehow stopped further processing of rules, one way or another.
