Mac OS 9: USB Adapter Card Support

I've installed Mac OS 9, but am now unable to use a PCI USB adapter card in my Power Macintosh. The vendor of my adapter card(s) has referred me to Apple.
In some instances it may be necessary to re-install the latest version of USB Adapter Card Support after installing Mac OS 9 in order to restore function for USB PCI Adapter cards.

The latest version of USB Adapter Card Support can be obtained from the Apple Software Updates Web site at http://www.apple.com/swupdates.
