Sorry, I doubt whether any of my suggestions would be of any assistance, as I understand that alcatel have updated the speedtouch once or twice, since I was having mega snags with mine (the one that looks like a turquoise cow shit!
I seem to recall that when I installed version 9.0, I only had to copy the microcode into /usr/share/speedtouch and then ran the wizard, then I just went to connect and it worked.
If you search here at LQ for "speedtouch adsl" or variations of alcatel speedtouch usb modem adsl, you should kick up a fair number of thread that COULD have a few clues.
Oh, and I also had it so it would start at boot, so if I wanted net access, I just clicked the browser. I also seem to recall having to switch of the firewall to start with, as I never did manage to get "shorewall" (which was the default offering of firewalls from mandrake).
Failing that, there's the slightly more expensive option (that I went for eventually because it used to piss me off waiting the the connection to drop/reconnect when switching OS's) and that's get a network card and a modem router (I use a solwise SAR110, now superceded by the SAR130), even a nugget like me managed to configure it, and now I let that handle the connection and firewall.

you might not get answers as quickly as you do at LQ, but it's distro specific, and while some of the possible solutions will be the same as the ones that you get at LQ, some might not!, worth a try any way.
