Hi, I am having trouble with an external USB DVD burner LG GP60NB50 (HL-DT-ST DVDRAM GP60NB50 1.00) on FreeBSD 9.1 amd64 and 10 current amd64. The drive burns normal DVDs and CDs but fails to write DVD-RAM. DVD-RAM burning is 100% supported with this drive, managed to test it in Linux as well - all worked OK. The error I am getting with DVD-RAM running "dd if=/dev/zero of=/dev/cd0 bs=2k count=1" is: (cd0:umass-sim0:0:0:0): WRITE(10).

Tried DVD-RAM burning with the same media in FreeBSD 9.1 on a different laptop with an internal DVD burning drive and that worked flawlessly. Also applied USB quirk to force ATAPI protocol but that hasn't helped either. Please could someone shed light on this and possible causes? Thanks!
Hi, Maybe mav @ knows. This is not an USB issue. --HPS _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
