getting USB CDRW to work

[Sebastiaan <S.Breedveld@ewi.tudelft.nl>]

Hi!

I am trying to get an external USB CD writer to work.

I bought an empty USB<->IDE case and it works fine for harddisks. With the
CDRW drive I can mount CD's with no problems. Unfortunately, cdrecord
doesn't recognize the drive as being a writable device.

The drive is a Lite-On LTR32123S. On connecting the USB device, the kernel
spits out these messages:
kernel: usb 1-2: new full speed USB device using address 4
kernel: usb 1-2: Product: USB 2.0 Storage Device
kernel: usb 1-2: SerialNumber: 00042222200000119603

kernel: UDF-fs: No VRS found

On 'cdrecord --scanbus', it detects:
        2,0,0   200) 'Revoltec' 'USB/IDE Bridge (' '0103' Removable Disk

and is unable to use it as a write device.

I am using 2.6.8.1 on a i386 architecture, running Sarge.

Any hints on this?

Thanks in advance!
