Yes, even if I couldn't remember the list address. And nor could Justin.

This bit is suggesting that usbdevfs might not be mounted.
What does the output of "mount" look like?

This bit is a load of junk output caused by trying to start PPP running
across a device which doesn't exist.

A hub. Possibly internal.

And yet another hub, apparently.
You seem to have four busses, each with a hub and nothing else. This
suggests to me that the device isn't plugged in, or else Linux has
somehow got confused about what is and isn't plugged in.
To be fair, this output is somewhat beyond me, and I may be
misinterpreting it totally.

Likewise, this tells me that you have four USB buses, with no devices
attached.

Not sure you need this, it's PPPoATM. Last I looked, Benoit's driver

More IP tables support. (Including NA[P]T support, which is a horrible
aberration, but works just enough to convince people it's worth using.)

I suspect YAST has tried to load in a bunch of the original Alcatel
drivers, including PPPoATM support in the kernel. In addition, you
haven't got the HDLC driver loaded, which I'd expect to see. (It's
called n_hdlc). Nor the ppp_synctty support I'd expect, either.

This is the "Host Bridge". It has trolls hiding underneath, which
multitask between charging money in exchange for not eating the data,
and threatening goats who try to eat the lush green PCI cards.
Um. Okay, I vaguely think it's something to do with linking the CPU to
the PCI bus, or something similar, but I don't really know. Every PC has
one, that much I know.

AGP interface. I suspect this is only used by PCI cards which transfer
data directly to the video card, but I'm not sure.

IDE, which we think, looking at your driver listing, has a CDROM on it.
Most likely it has your hard disk on too, but that driver isn't visible.

And there we go - four USB controllers, which ties in with the above.
What's weird is that the fourth is EHCI. You might want to consider
moving the Speedtouch to a different USB slot, since they might be
interfering somehow.
Martin [SlayerXP], my infamous colleague, comments on IRC:
<dwd> SlayerXP: What I find odd is that his motherboard has three OHCI
controllers and one EHCI.
<SlayerXP> dwd: that's not impossible
<SlayerXP> the OHCI controllers may really be "legacy" devices
<SlayerXP> tell his to check his BIOS config

My strategy would be:
1) Tell Yast to uninstall anything to do with the Speedtouch. I'm pretty
sure you've got two distinct drivers running.
2) Check BIOS settings regarding the possible legacy USB devices.
Changing the setting might confuse Windows a little. See if lsusb sees
the modem.
3) If not, move the SpeedTouch from slot to slot. See if lsusb sees it.
4) If you still can't see the modem with lsusb, then take the hardware
to the next LUG meet, hand it to Alan to fix, and utter the magical
incantation, "Of course, if it's too difficult for you to fix..." ;-)
Seriously, I've no idea at this point.
5) If you can see the modem, now, then see if usbdevfs is mounted by
looking for it in the output of "mount".
6) Run "modprobe n_hdlc ; modprobe ppp_synctty", to manually and nastily
pull in the right drivers. (This can be done automatically later)
7) Try the modem start script.
8) If all else fails, start stocking up on rats, candles, and obsideon
knives.
Hope this gives you somewhere to start.
Dave.
