My 7500 PPC has a Powerlogix G3 upgrade card in it. I put in a Keyspan PCI card with 2 USB ports in order to use an Epson printer. Everything worked fine until recently. I upgraded the OS to 9.1. The Epson wouldn't work so I tried to reinstall the driver from Apple for this card. The driver will not install. It looks like it goes all the way through the install process but when I go into the control panel for the card settings it tells me that there is no driver installed for it. I checked the Apple Profiler and it recognizes the PCI card. I'm not sure what to do now. Anything I should be aware of regarding OS 9.1 and the Keyspan USB PCI card?
