I think that's a normal message - I forget the reason, but it was in the
userland speedtouch driver HOWTO. I've always got them every time I
start up the modem:

Mar 28 11:41:57 z kernel: hub.c: USB new device connect on bus1/1,
assigned device number 2
Mar 28 11:41:57 z kernel: usb.c: USB device 2 (vend/prod 0x6b9/0x4061)
is not claimed by any active driver.

Mar 28 11:42:16 z modem_run[24088]: ADSL line is up (576 kbit/s down |
288 kbit/s up) 

Do you get anything else in the logs b.t.w.? Is the machine totally
wedged when this happens?

Hmmm - since you say "laptop" I'm presuming that it is not the same
machine, so it could still be that the is a problem with USB on the
other machine. A mouse might not be enough to exercise the problem
(quite a slow device c.f. the modem). Anyway, it sounds like the modem
is fine, I'm not sure you be certain about the host hardware.

I'm not sure what usbview is, but if you're using the userland
speedtouch driver then there won't be a hotplug kernel driver for it,
and from the system's point of view nothing is looking after it
(speedtouch uses some sort of raw access to the device) so I could
imagine it being listed as "not working" in a spurious way.

Assuming for the moment that it isn't the hardware it might well be that
something else has changed - system updates, for example. From the above
it doesn't sound like your system is completely stuck, so you could try
manually doing each step of the modem initialisation and seeing where
the problem occurs.
