If you install a fax modem and Windows does not detect or install the modem drivers automatically, you’ll need to install the proper drivers provided from the manufacturer. This can be a problem if you do not have the driver files, and you don’t know the name or model of the fax modem.
If you are unsure what model of fax modem you have, you can check the device properties to determine what brand/model you are attempting to install.
This can be done by checking the VID and PID values of the device that is attempting to be installed. The PID value provides you the Product ID and the VID provides the Vendor ID (the modem manufacturer, or chip-set manufacturer) such as Conexant/Rockwell, LSI/Agere, Motorola, etc.
In device manager, go to “Modems” and check if a modem name is listed here. If so, double-click the Modem name listed here and then click Details Tab. Select and Scroll down to “Hardware IDs” in property and here you’ll find the VID (Vendor ID) and PID (Product ID) (example is VID_0572&PID_1300)
If the modem is missing then the default Windows driver could not be installed and Windows will allocate the modem under an “Unknown Device” heading. If you double-click the Unknown Device and click Properties, Details tab you should have the PID and VID or VEN and DEV values displayed here. You can then search based on the VID and PID values.
Searching Windows Catalog for drivers
Windows provides an extensive list of drivers, you can search here and download the compatible drivers that available on Window Update.
https://www.catalog.update.microsoft.com/
Type your search string, for example “PID_1329” will display all compatible drivers that contain the PID 1329 or enter “vid_0572” to display drivers that contain vendor ID 0572
Searching for Vendor ID or Product ID
If you are unsure who the vendor, or product id you can search https://devicehunt.com/ or http://www.pcilookup.com/ for information on Vendor ID or Product ID. Note that USB device information may not be available on these sites.
