OK. I forgot to mention that this USB controller is a PCI card Ali
chipset USB controller. 6 port 3 front/3back.

The front ports are what are giving me problems with the zip drive. I am
receiving the "USB disconnect" message when using the back ports. 

I ran a test, plugging my Lexar USB 2.0 multi-card reader into the three
front ports and all three gave me the "USB disconnect" message when I
unplugged it.

Using the back port(s) is not very convenient because of my computer
placement. Is it safe to plug/unplug a device from the "D" shaped end of
the cable? Leaving the cable plugged into the port and just unplugging
the device. I have extra cables which would allow me to do this.

I can mount/unmout from the command line (as root). When it is unmounted
the icon disappears. Mounting/unmounting doesn't seem to be any problem,
nor does reading/writing to the disk.

OK. I tried that and it didn't make any difference. Is the effect
permanent or does it change after a reboot?

Thanks again for all your time and help.
