.....
I use only Lite-On CD/DVD burners, internal and USB external, in and plugged
in, on desktops and laptops, and they work with Linux. Have always done, so
when on a good thing, I stick to it.
But in Debian they don't work with the 2.4xxx kernel with K3B, and scsi
emulation make no difference other than vanishing the external device. It
seems that growisofs eats the device if scsi emulation is used. There are
some things on the Internet about this. K3B use eats the external USB Lite-On
because /etc/fstab lists it as an scsi device.
I cannot understand the growisofs way of creating a DVD, [more reading
required] so burn CD's as backups. XCDRoast works a treat without any
problems. Especially on the external Lite-On device.
That may or may not help.....
