It uses the Agere chip, as reported by Vi$ta. Is it hardware then?

Based on the review here, where someone got it to run in
Linux, using just an init string, it would have to be
a reasonably intelligent device.

Is there 2 Agere chips (one software, one hardware)?

Agere was bought by LSI Logic. The Agere site was partially
protected by "no robots" exclusion, so web.archive.org has not
backed up all web pages. But this document shows that Agere
made chips that supported controller-less, as well as
controller-based solutions.

http://web.archive.org/web/20040612092505/http://agere.com/docs/client_final.pdf

I hope Vista has identified the chip for you, because it may
be difficult to identify it exactly otherwise. The USB.ids
file I have, doesn't have a lot of entries for Agere. If you
still don't know what chip it is, it may be faster to just
take it apart with a screwdriver, and have a look. (Read the
part number off the top of the chip.) When you look inside,
there has to be some solution for the DAA, the part that
connects to the phone line, while the logic chip that does
USB and provides a data pump (or not), would be separate
from it. The telephone signals involve high voltages, and
part of the job of the DAA, is to separate the dangerous
part of the telephone network, from the rest of the circuit.

Vi$ta identified it as "Agere Systems USB 2.0 Soft Modem". I didn't
expect the "Soft" word given the description in US Robotics' website on
5637....

Does Vi$ta list all USB modems as soft-modems?

Not an electronics person myself and it would void the warranty if I
opened it too soon. Thanks for the explanation.

A good question. At this point, I don't even understand
the Vista driver model, as to where the drivers are coming
from. Vista seems to have more drivers built in. Maybe you
can try the program below, and see if that string appears or not.

You would use a program like UVCView, to get the VID and PID numbers
for the device. But the thing is, if the USB.ids file doesn't define
very many of the Agere chips, it would be hopeless to discover more
about them. The fields you'd want to record, would be
idVendor and idProduct.

Still, give this a try and see if it runs for you. I'm
not aware of any respondent trying this one in Vista,
so you'll be the first.

By the way, the second link above (for UVCView.x86.exe), belongs
to the other guy who responded in this thread :-)

To give you an example, I just plugged in my spare USB mouse.
This is the data shown for it. idVendor is 0x03EE and
idProduct is 0x6407. Those are the "VID and PID". When I
go here, only the value for Mitsumi is listed, and not
the part that says it is a mouse. The reason this listing
is not complete, is it is not the official listing. The
official listing is secret, and not for public usage.
This listing is prepared, by people reporting what
they find for themselves.

So you're a long long way from learning anything more
about your modem.

The reason this listing
is not complete, is it is not the official listing. The
official listing is secret, and not for public usage.

I have extracted all the coded IDs from UVCview and Usbview:

http://www.users.on.net/~fzabkar/USB_IDs/usbview_vid_nam.txt
http://www.users.on.net/~fzabkar/USB_IDs/uvcview_vid_nam.txt

I submitted the list to www.linux-usb.org a long time ago, but
incorporating it into their usb.ids must have looked like too much
hard work. :-(

The datasheet says it's controller-based, so according to USR it must
be a full hardware modem. Lucent/Agere internal hardware modems were
often based on the Venus chipset, but I don't know about the USB
versions. If you can peek inside the box, look for two support chips,
a static RAM with a part number like 61xxx or 62xxx, and a flash
EEPROM with a number like 29Fxxx. The presence of these chips would
confirm that your modem is hardware based, although their absence
would be inconclusive.

A clue as to whether your modem is soft or controllerless would be in
the size of the drivers. A USB hardware modem would only need drivers
to handle the USB interface. The rest of the hardware would only need
an INF file.

Another clue would be to make changes to the modem's registers, store
them in NVRAM with the AT&Wn command, and then see if these changes
follow the modem to a different PC.

FWIW, you can tell whether your modem has a silicon DAA or one based
on a mechanical relay by listening for clicks during pulse dialling,
with the speaker muted.

The following command should do it:

AT L0 M0 DP your_modem's_own_phone_number

That doesn't tell you anything about the other chips, though.

If your modem can be flash upgraded, then the fact that it has
firmware would confirm that it is hardware based.

What do the ATIn commands report? Sometimes they report the actual
chipset names. I don't know about Vista or XP, but Win98's Control
Panel automatically generates a list of ATIn responses when you ask
for More Info under the Diagnostics tab.

You can also query the modem with fax commands:
http://www.usr.com/support/5637/5637-ug/ref_fax.html

Try ...

AT+FMI?
AT+FMM?
AT+FMR?
