I'm waiting to see if anyone else has it working.

You could try this:
105933
Untick fax and scan, restart.
Tick it, restart.

Ok, so that suggests the driver is ok, modem ok, so the issue lies with the fax & scan program or its configuration...

I can't find similar issues reported (maybe not too many people use it these...

So you didn't get an error msg like this?
105843

(I don't have a modem in this laptop).

If you didn't get an error msg, that implies it is finding your modem. Can you actually dial a number?
...

Ok, try this:
In C:\Windows\System32 you should find dialer.exe

Double click it; it will try to find a modem.
See what happens.

When you connect your USB modem to your PC, is it recognised? Do you see any yellow...

Hi, presumably you're using Fax & scan.
Could you be a little more specific in which aspect of setting it up isn't working?
Is this a pure software issue, a modem issue or something else?

Could...
