Let's have a looksee.

There's one USB bus and it's USB 1.1.

There's a second bus and it's USB 1.1.

There's a third bus, USB 1.1.

And there's a fourth bus, USB 2.0.

The system is having trouble with the third USB bus.  You should check
the cables there.

There's a potential issue there on port 4 of the USB 2.0 bus.

It appears that you have a whole bunch of USB ports.  I counted three
buses there, two with 2 ports and two with 4 ports.

It looks like your ZIP is in bus 2 (one of the two-port buses that's
USB 1.1).  The system is having an issue with bus 3 (the other two-port
USB 1.1 bus) and it can't reliably debounce one of the ports.  Check the
cable there.

Bus 4 (one of the 4-port buses and the only USB 2.0 I see) reports a bad
port, and I suspect that's where the external HD is plugged into.

There are several possibilities: The bus is USB 2.0.  If your drive
is also USB 2.0 compliant and you use a USB 1.1 cable, you'll have
issues.  I'd recommend first checking your cables.  Try to always use
USB 2.0 cables--even if it's a 1.1 bus.

You may have a bad port on that bus.  You might try a different port on
that bus.

Try the other 4-port bus (USB 1.1, so it'll be slower).
