misha Tl Posts: 16 USA | Posted - 2/13/2003 11:35:29 AM I have good controller based USR Voice modem model 2976 (3CP2976-OEM-50)but it does not get recognized under Windows 2000. This is OEM modem, so they won’t support it (see their response below). The driver(or .inf file) that is on USR support web site does not make Windows 2000 to recognize this modem. Did anybody tried to make this modem work by modifying .inf file or if any other model’s .inf can be used to for this modem? It is very good modem and I hate to waste it because this problem. Thank you. Reference: I have 3CP2976-OEM-50 modem that used to work fine under Windows 98. So, the After extracting to the folder on the floppy, got the following files: The executable (I believe the install program) that came with those drivers ============== What I got from USR support ======================== Re: Email ID 2851349 Dear Sir/Madam, Thank you for choosing U.S.Robotics. Here is a link to OEM drivers: Download drivers from this link at your own risk. Please also consider
Here is a list of OEM support numbers: Acer Technical Support: (800)445-6495 USR provides some OEM drivers at the following website: If you cannot locate your modem drivers, you can try the following: *mdm3com.exe from ftp://ftp.usr.com/usr/dl07/mdm3com.exe for 33.6k and 56k
I would like to thank you for the opportunity to assist you. Should you Again, thank you for choosing U.S.Robotics.

charles Tl Posts: 5879 USA | Posted - 2/14/2003 1:17:13 AM This modem has alot of names but might also try this. http://www2.driverguide.com/uploads/uploads10/3352.html This is from the readme file on install. If Windows is detecting new hardware called a PCI SERIAL PORT, skip to step 5 |

charles Tl Posts: 5879 USA | Posted - 2/15/2003 12:38:32 AM Your welcome glad it work out. |
misha Tl Posts: 16 USA | Posted - 2/15/2003 11:03:57 AM I noticed that modem can not negotiate speed faster then 31.2 Kbps. Under windows 98 it was connecting 44Kbps and faster. Maybe I did something to Windows 2000 by installing and uninstalling many different modems? Are there any additional settings to make it connect faster. Michael

charles Tl Posts: 5879 USA | Posted - 2/15/2003 12:48:18 PM Check your dun settings also. http://modemsite.com/56k/connectoid2ke.asp http://modemsite.com/56k/diag3com.asp http://modemsite.com/56k/x2-hyperterm.asp Do you have any nic card installed? What com port is the modem on.aslo what drivers version are you showing installed? |
misha Tl Posts: 16 USA | Posted - 2/15/2003 2:11:58 PM Hello and thank you again for your help. My modem is installed on COM3, IRQ 18. I have disabled COM1 in my BIOS. Com2 is available. My Control Panel/Device Manager does not show any conflicts. I have build-in on-board network card and it is connected to my home Hub. No other devices are connected to this hub. Sometimes, I connect my laptop to the hub to exchange data between my laptop and desktop. The card may be the problem: in my old system I have different PCI network card not on-board one. But I don’t see any conflicts. Network card uses IRQ 20.
This is my Log: About Drivers: Maybe too many different drivers confuse my dial-up system? Terminal ==================================================== OK
150 20 =====================================================================

misha Tl Posts: 16 USA | Posted - 2/15/2003 2:12:25 PM At least the connection at 31000 is stable. Other modems (5610, 5610A and 5610B) have connected at higher speed (45-51) but they sometimes got into "frozen" state - no in/no out but still connected. I found that those modems had "unrecognazed responce" entries in their modem logs. Does this ring any bell? Thank you. Edited by - Misha on 2/15/03 2:19:22 PM |
charles Tl Posts: 5879 USA | Posted - 2/16/2003 3:06:49 AM First of all, if the value of 3750 is above 50, you may have poor local phone lines and may want to check into noise. Now, take the level of 3300 and subtract it from the level of 3750. If the value is 25 or higher, you most likely have too many A/D, D/A conversions which indicates that you can not achieve 56k speeds. If the value is between 20 and 25, you MAY have too many A/D, D/A conversions and you may not be able to achieve 56k speeds. 3300 20 3750 29 The line looks fine but will work on this more when I get time.Also could use the ATI6 and ATI7 |
misha Tl Posts: 16 USA | Posted - 2/16/2003 8:36:25 AM I will try outside phone box and I let you know. I do have a surge protector that is a part of my UPS (uninterruptible power supply) but I tested modem without it and I also tested it with different phone outlets. Same result. The line is about 16 feet with no devices in between my modem and a phone pole. I will check outside box too. I had problem with it a log time ago. Also, on Monday, I will try bring my laptop from work and make it connect to ISP using my modem’s outlet to see if it will also get a low connection speed. I suspect that one of my phone lines may have some shortage. I will test all lines with ohmmeter. What I know for sure is every time I dial, my modem tries to negotiate normally (V.90) and then 2-3 seconds pause after which it negotiate a lower speed. Than you for your willingness to help.
