My CD-Writer HP 8200 series is on a usb port and seams not to be detected properly by my kernel. An extract of /var/log/messages shows it as detected as follows:
Aug 8 13:53:11 mirse kernel: Uniform CD-ROM driver Revision: 3.20
Aug 8 13:53:11 mirse kernel: Vendor: HP Model: CD-Writer+ 8200e Rev: 0001
Aug 8 13:53:11 mirse kernel: Type: Direct-Access ANSI SCSI revision: 00
But once my Mandriva 2006 Linux is running, I hear constant drive stop and start from the cd writer, and from messages similar to the following are logged to /var/log/messages and/or syslog:

What is my problem, ... and its solution?
