scanner and digital camera model that's works on knoppix 3.6

I have download knoppix 3.6 and tested the following problem and it still cant works.

Previously I am using knoppix3.3 and tested the internet dial-up successfully. Now, when I used the knoppix 3.6, I can dial-up using the same modem but can not browser the Internet through Mozilla or knoqueror. The modem status is connected. But it seem when I open a browser, it always display page not found.

I have tested scanner Mustek BearPaw 2448TA Plus, but it seem cant detect the scanner (in SANE website it said it can works). How to make it works?

For digital camera Ricoh RDC-300, it has the model in the gtkam but it cant seem to work also.

Please help me with these three problem.

Thanks in advance.
