Today I have used my recently acquired Lenovo USB 2.0 Super Multi-Burner Drive to burn a CD from Gentoo GNU/Linux. I used the following command,
cdrecord -v -v -tao fs=16m dev=/dev/sr0 -data FILENAME.iso
and tested it by adding a -dummy option before the -tao. The drive shows up as /dev/sr0 on my X60s system.
