I just bought an HP DVD Writer 1040r (as identified by k3b), an external USB-connected CD/DVD burner. The drive gets assigned /dev/scd0. I can burn CDs and DVDs, read from CDs and DVDs, boot from DVDs (and, I assume, CDs) but have been unable to use the lightscribe software to label a disk. I have lightscribe-1.18.11.1-0 and lightscribeApplications-1.18.6.1-0 installed, can run the GUI at /opt/lightscribe/Applications/SimpleLabeler/SimpleLabeler which promptly and stubbornly tells me "--<no lightscribe drives found>--". This IS a lightscribe drive, according to the specs, the box and the logo on the tray. This is on a fully update CentOS 5.4 system that has behaved very well since I built this box (Gigabyte MA770T-UD3P) about 3-4 months ago. This is certainly no a critical situation but having new stuff that doesn't work is rather irksome to me. Can anyone offer a clue or two? Thanks!
