Win98 Installs Two Instances of Modem
Posted on 2002-07-20
I'm working on a computer where I had to remove a bad PC-TEL HSP ModemRiser and which I replaced with a a new HSP standard PCI modem (not a riser card). Win98 detects the the new modem as a PCI card and installs it properly using the drivers on the HSP CD-ROM. The modem works fine.
However, Win98 also detects a "PCI Communications Device" and, if I let the installation process continue, another modem is installed and neither will work. Each time I reboot, the PCI Communicaions Device detection appears and I must cancel to prevent installation of the second modem instance.
Prior to installing the new modem, I removed the PCI ModemRiser software, searched the registry and deleted all apparent references to the original HSP modem in order to make a clean install but Win98 still tries to install another modem instance after the first one is installed and working.
How do I prevent Windows from detecting the PCI Communications Device (other than pressing "cancel" on each reboot) so that the new modem will work properly.
