From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jan Evert van Grootheest Date: Fri, 26 Nov 2004 13:04:46 +0000 Subject: unsupported USB/IDE bridge? Message-Id: <41A729EE.1090201@hccnet.nl> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: linux-hotplug@vger.kernel.org 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?
