Go back and read the message closely. It says the _driver_ was registered, not the _device_. > If not, could you please explain me more what was I missing > and how can I fix the device registering?

Like Greg said, you should try other USB devices on that system and see if any of them work. Also, ISTR your earlier message indicated that you were using a 2.4 kernel. If that's right, you should make every effort to upgrade to a recent 2.6 kernel. Alan Stern ------------------------------------------------------------------------- Using Tomcat but need to do more?
