Here are a couple of ideas.
1) Turn the printer on before you start the computer. That way it will not depend on the hotplug to register it since it will be seen and registered during system startup.
2) Use YaST to configure it as if it was a new printer.
3) Check to see if the CUPS daemon is running.
Code:
user1> ps ax | grep cups
2331 ? Ss 0:00 /usr/sbin/cupsd
22809 pts/0 R+ 0:00 grep cups
If it is running then use a web browser and point it to this address;
localhost:631
Then look to see if the printer is already configured. If it is then delete it and start again.
I had been using SuSE 9.2 until a week ago. I could never get my Epson C84 to work through the USB port but it was very reliable when I used the printer port. Sometimes the old ways are best.
