unsupported USB/IDE bridge?

unsupported USB/IDE bridge?

[Jan Evert van Grootheest]

Hi,

I bought an USB/IDE bridge and put a DVD-RW in it. Now if I plug it in, 
it gets assigned /dev/sda by the kernel. Not bad at all, I thought. And 
it reads CDs and DVDs just fine.
But, unfortunately, I can't (yet) write with it.
Checking the logs I found the lines below when re-plugging it.

Those lines request mailing here.

Some other info: this is a Duron 700 running debians 2.6.9-1-k7 kernel.
Udev and hotplug are (according to dpkg):
ii  udev                    0.042-1                 /dev/ management daemon
ii  hotplug                 0.0.20040329-16         Linux Hotplug Scripts

If any other information is required, just ask.

While I'm here, any suggestions how to get this DVD writing?

Thanks,
Jan Evert
