[SOLVED] Missing /dev/sr0 for USB CD drive

I have two computers running Arch, plus a USB CD drive. One one computer, when I plug in the CD drive, /dev/sr0 isn’t created. This is the dmesg output:

[1329021.990045] usb 1-8: new high speed USB device number 8 using ehci_hcd
[1329022.142054] scsi8 : usb-storage 1-8:1.0
[1329023.144288] scsi 8:0:0:0: CD-ROM            TSSTcorp CDDVDW SE-S084C  TS01 PQ: 0 ANSI: 0

But when I plug the CD drive into my other computer, everything works fine:

[14489.540448] usb 2-1.4: new high speed USB device number 12 using ehci_hcd
[14489.653652] scsi7 : usb-storage 2-1.4:1.0
[14490.652788] scsi 7:0:0:0: CD-ROM            TSSTcorp CDDVDW SE-S084C  TS01 PQ: 0 ANSI: 0
[14490.664000] sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
[14490.664305] sr 7:0:0:0: Attached scsi CD-ROM sr0

Running mknod to create /dev/sr0 on the first computer doesn’t help. The drive works fine on my second computer, and it used to work on my first computer. I think the last time it worked on my first computer was when I was still running initscripts. I’m using systemd and the 3.0.65 kernel on both computers.

Any ideas?

Can you post the output of the following:

pacman -Qi linux linux-lts
uname -a

I looked at the output from those commands, and realized that I had installed linux-lts 3.0.65 on both computers, but hadn’t rebooted one of them, so it was still running 3.0.64. I rebooted that computer and everything works now. Oops.....

Problem solved—thanks.
