9.1 and Philips CDRWDVD2010

Hello, can somebody help me? I have an old PII with Philips CDRWDVD2010 CD-R/RW writer/DVD reader combo. I'd like this use a server and write daily back up. 9.1 recognized writer, but not created /dev/srx link. If I create manually cdrecord -scanbus not detected it. The k3b can write CD, but not set up speed correctly. What I make wrong? Thanks steve
