I have suddenly gotten a message Software needed for the USB device
"harmon/kardon USB iSub" is not available. This is on the first slot
loading iMac using OS 9.2.2. I have spent several hours searching to no
avail.

Any suggestions?

Did you recently install any other software? It may have installed an
extension that interferes with the Apple USB extension that runs the
iSub. What happens if you reboot with the minimal Apple-only extensions?

When I reboot with the miminal extensions, I get basically the same
message. Surprisingly, after the message, a minute or two later the iSub
starts working.

Do you happen to know what extension has the iSub driver?

Thanks for your response.

As far as I know, there isn't a separate iSub extension. It's run by the
standard Apple USB Device Extension I think. The content of the error
message would seem to indicate that the Mac sees the iSub (it shows up
in Apple Profile right?), but that it can't continue. Maybe hardware: I
once had a problem with too many USB devices and hubs that killed my
iSub. The iSub takes a lot of power, and may not work on a hub or via
the keyboard hub. Maybe try rearranging your USB devices, and giving the
iSub its own port on the iMac.

I have found to ignore the message. The iSub starts working after a few
seconds. Go figure!
