I managed to run my speedtouch 330 with RH 9.0 with the script u can find at
www.sourceforge.net.
Download the Speedtouch Configuration script, unpack it and run it.
It's simple and, MOST OF ALL, the only one that works.
You'll find that the modem rus even faster on Linux that on Windows.
Let me know if it works also for you.
Bye alex
