external dvdrw installations
Hello all,
Please can someone assist?
I am attempting to install an external dvdrw on fedora 6.
I attach the dvdrw device to the USB port and run dmesg:
scsi2 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 4
usb-storage: waiting for device to settle before scanning
scsi 2:0:0:0: CD-ROM SONY DVD RW DRU-710A BY01 PQ: 0 ANSI: 0
scsi 2:0:0:0: Attached scsi generic sg0 type 5
usb-storage: device scan complete
sr0: scsi3-mmc drive: 62x/62x writer cd/rw xa/form2 cdda tray
Uniform CD-ROM driver Revision: 3.20
sr 2:0:0:0: Attached scsi CD-ROM sr0
I presume the system has picked up the device and check /dev:
# ls -lrt /dev
brw-rw---- 1 root disk 11, 0 Mar 28 14:35 scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 dvdwriter-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 dvdwriter -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 dvd-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 dvdrw-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 dvdrw -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 dvd -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 cdwriter-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 cdwriter -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 cdrw-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 cdrw -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 cdrom-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Mar 28 14:35 cdrom -> scd0
I try to mount the device however get the following error:
# mount /dev/scd0 -t iso9660 -r /mnt/usbcdrom
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
missing codepage or other error
(could this be the IDE device where you in fact use
ide-scsi so that sr0 or sda or so is needed?)
In some cases useful info is found in syslog - try
dmesg | tail or so
can anyone tell me where I am going wrong? I have read several documents but cant seem to find any useful info.
many thanks
chris

EHCI(4) BSD Kernel Interfaces Manual EHCI(4)
NAME
ehci -- USB Enhanced Host Controller driver
SYNOPSIS
device ehci
DESCRIPTION
The ehci driver provides support for the USB Enhanced Host Controller Interface, which is used by USB 2.0 controllers.
EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol. This means that they normally have one or more companion
controllers (i.e., ohci(4) or uhci(4)) handling USB 1.x devices. Consequently each USB connector is electrically connected to two USB con-
trollers. The handling of this is totally automatic, but can be noticed since USB 1.x and USB 2.0 devices plugged in to the same connector
appear to connect to different USB busses.
SEE ALSO
ohci(4), uhci(4), usb(4)
HISTORY
The ehci device driver first appeared in FreeBSD 5.1.
BUGS
The driver is not finished and is quite buggy.
There is currently no support for isochronous transfers.
