On this page you will a find a short guide on how to set up a Sony DRX-820UL
I wrote it because when I searched google I found nothing about this Hardware.
All comments, suggestions etc. are welcome. Please contact me at firstname.lastname@example.org.
Let's have a look at the easy stuff first.
You need the following configuration in the kernel (here at the moment 2.6.14):
# USB support
# USB Host Controller Drivers
# CD-ROM/DVD Filesystems
Plug in the USB cable on the computer's side and into the DRX-820.
The drive is recognized as
Vendor: SONY Model: DVD RW DRU-820A Rev: 2.0b Type: CD-ROM ANSI SCSI revision: 00
and the mass-storage driver should be loaded automatically (here that works even with usbmgr, hotplug isn't a problem either).
Now you can address the DVD drive as
/dev/scd0, if it is your only
SCSI (emulated) CD/DVD drive, else
/dev/scd1 and so on.
You can eg mount a DVD by running
# mount /dev/scd0 /cdrom
mount: block device /dev/scd0 is write-protected, mounting read-only # mount /dev/scd0 on /cdrom type udf (ro)
Plug in the firewire Cable (it doesn't matter which port you choose on the DVD drive).
Load the modules ohci1394, sbp2 if they are not loaded automatically.

Using gscanbus to see the drive doesn't work here. Im just looking into this.
The drive neither shows up in cat
