USR5661A (USR805661A)
Posted by Nick Le Lievre on January 9th, 2006


I found a Compaq Deskpro EN PII266 dumped. Out of interest I picked it up and
discovered that the modem wasn't working (Win98) I looked at the modem and
found its support page

http://www.usr-emea.com/support/s-pr...mea&prod=5661a

The driver already assigned to the modem was US Robotics v.92 which sounds
right but trying to reinstall the modem with that driver Windows says it was
not written for it. So I'm going to download the one from the support page to
make sure. Plug n Play detects it as a PCI Simple Communications Controller as
it has no driver to identify it. Also do US Robotics modems use different wired
modem cable then a conexant based modem TIA. Reply to group or email (delete

composed:

FWIW, I suspect your modem may be a rebadged Conexant HSF softmodem.

Ok the driver works and my modem cable is wired correctly on another modem I
had to use this init string to connect to my ISP;

+MS=V90,0,,,44000,52000

Could some kind person look at the AT command set for the USR5661a which is
available here

http://www.usr-emea.com/support/s-pr...mea&prod=5661a

Its in .pdf format and I can't read it atm and tell me the init string I need
to do what the one above does - thanks very much.

Its OK the init string +MS=V90,0,,,44000,52000 works for this USR5661a also
which as you say must also be a conexant based modem (same as the other
modem).

I have to say also that I installed my copy of Windows 2000 on the PC and
then downloaded the driver from that webpage.

I suspect the reason why the driver had stopped working under Win98 was
because the someone must of tried to uninstall/reinstall the modem
incorrectly this messes up the registry settings (I know seen the problem
before about 6 years ago).

The drivers I downloaded from the web included a setup utility and it was a
clean registry + Windows 2000 drivers are probably better.

sort of modem it is would be to put it in terminal mode (perhaps using
hyperterminal) then issue the following commands (each followed by the enter
key): AT&F, ATI1, ATI2, ATI3 through to about ATI11 - note that some may
generate ERROR and if so, thats nothing to be alarmed about. See what the
responses are - this will usually tell you among other things, the
manufacturer (or at least the chipset manufacturer), the firmware version
and other useful info. If you "query modem" in the windows control panel
modem diagnostics tab, it will also show you some ATI responses (not sure
what happens if modem isn't correctly installed though so use hyperterminal
if this doesn't work).
