Adding an USB PCI card on a PowerMac 6500

I have a PowerMac 6500/300 with a Sonnet Crescendo L2/G3 500 Mhz upgrade card, 128MB RAM and my operating system is Mac OS 9.2.2. I had to fix the system file with ResEdit to get this OS working on my Mac. I have a problem with a recently installed Keyspan UPCI-2 USB 1.1 PCI card which I have imported from the U.S. to Switzerland. All the devices are recognized correctly in the Apple System Profiler (e.g. USB Hub, Zip 100, etc.) but no device is mounting on the desktop. All the USB and USB card drivers are installed from the Mac OS 9.2.2 CD.

Is it possible that the Keyspan USB PCI card denies working if a L2/G3 upgrade card is also installed? Does anyone have an idea what the problem could be?

pm6500, welcome to Apple Discussions.

It's possible that when you upgraded to OS 9.x that the necessary drivers didn't get installed if the USB PCI card was not installed. Try reinstalling OS 9.x. Also, some newer cards just don't work in older model Macs.

For future reference, there's a lot of good info on the 6400/6500 Macs at the 6400 Zone http://www.zone6400.com/

 Cheers, Tom 😉

Here is a list of the extensions that are loaded under OS 9.2.2. You will either need to re-install the Network section of the System, or extract most of these from the 9.2.1 update:

USB Extensions From Mac OS 9.2.1:

HID Library 1.5.5
USB Authoring Support 1.1.2
USB Device Extension 1.5.5
USB Mass Storage Support 2.1.1
USB Printer Sharing 1.0.2
USB Printer Sharing Extension 1.0.2
USB Software Locator 1.5.5
USB Support 1.5.5
USBAppleMonitorModule 2.1

From Mac OS 9.2.2

HID Library 1.5.6
SerialShimLib 1.5.6
USB Device Extension 1.5.6
USB Software Locator 1.5.6

If you are going to stay with 9.2.1, the second group will have slightly older versions, but I do not have the version numbers readily available.
