usb driver for os9

riall5, welcome to Apple Discussions.

You probably have the software alteady installed with OS 9.

What is the make & model of the card you installed?

Does it show up in the Apple System Profiler.

Most USB PCI cards with more than 2 USB ports will not work in older model Macs.

You don't exactly say what G3 model you have. If it doesn't have built-in USB, you may can use this software.

USB Adapter Card Support 1.4.1 Document and Software

This software cannot be installed on Macintosh computers with built-in USB ports. Read The Read Me before installing.

Hi, Tom -

There is an important note applicable to the separate download you linked to; it's on the download page for it -

" Important: Mac OS versions 9.1 and later include a later version of this software. Installing USB Adapter Card Support 1.4.1 over Mac OS 9.1, 9.2 or later could result in the USB adapter card not working."

Since the OP appears to be using OS 9.2.x, it would not be advisable for them to install that software.

Instead, Joerg Weiss has created a good User Tip identifying software components and versions to aid in getting such cards to work -

Hello riall5,

Sorry to hear you've had a visit from the USB gremlins.

My experience has been that the easiest way to install proper USB drivers is to do a clean re-install of the OS from a retail, full install, gold-9-on-a-white-background CD. (The problem is that unless you have the USB card installed at the time you install, the OS install CD doesn't "see" the need to install the USB drivers and doesn't install them) The clean re-install will give you a new system folder with the proper drivers (USB 1.5.5) installed and a "previous system folder" with all your old junque needing to be dragged over from old to new folder. You can also install by custom install or by use of the Tome Viewer utility, but you will still need that retail, full install CD. I find the clean re-install easiest.

Occasionally you will find that you have an incompatible Rev A motherboard, and others have reported that their Macs are allergic to certain brands of USB cards,but I have not had those problems.

When you have the proper drivers installed, you will be able to go to the Apple System Profiler, click on the "Devices and Volumes" tab and see up at the top left corner right under the "System Profile" tab, a line with 'USB 0' above it and '1.5.5' below as a sign you are set, recognised, and ready to go.

BTW, 1.4.1 drivers are from OS 8.6, and 1.4.6 are from OS 9.1.

Regards and good luck......Jon
