I'm using an external USB HP cd-writer cd4e, and I am unable to burn CDs. When I plug it in, I get the following output from the dmesg command: usb 1-1: new full speed USB device using address 2 Initializing USB Mass Storage driver... scsi0 : SCSI emulation for USB Mass Storage devices Vendor: HP Model: CD-Writer cd4f Rev: 1.0A Type: CD-ROM ANSI SCSI revision: 02 USB Mass Storage device found at 2 usbcore: registered new driver usb-storage USB Mass Storage support registered. sr0: scsi3-mmc drive: 20x/20x writer cd/rw xa/form2 cdda pop-up Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0 When I attempt to burn using "cdrecord --dev=/dev/sr0 FC2-i386-disc1.iso" I get: scsidev: '/dev/sr0' devname: '/dev/sr0' scsibus: -2 target: -2 lun: -2 Warning: Open by 'devname' is unintentional and not supported. cdrecord: No such file or directory. Cannot open '/dev/sr0'. Cannot open SCSI driver. cdrecord: For possible targets try 'cdrecord -scanbus'. Make sure you are root. cdrecord: For possible transport specifiers try 'cdrecord dev=help'. When I do "cdrecord -scanbus" as root, all it sees is my standard cdrom drive.
