Hi Stephen,
Actually, the scanner is not plugged into an external hub.
It is plugged directly into the USB port on the motherboard,
and is the only USB device connected to the system.
And this, in fact, could be the problem - the system may be
accidentally configured to use an external USB hub.
When I run 'usbview' I see one of the following:

What does this mean? A assume that:
"USB UCHI ROOT Hub" refers to one of the two USB ports on
the motherboard.
"hub" refers to an external hub that the system 'thinks' is
connected to one of the motherboard USB ports.
Is this correct? I'm not sure about this.
If so, that could be the problem. So, how do I tell
the system that I don't have an external hub?
Incidentally, when you expand the "hub" entry, it reads:
hub
Speed: 12Mb/s (full)
Number of Ports: 4
USB Version: 1.10
Device Class: 09(hub )

Here, the Vendor Id: 0424 Product Id: 0140, is some 'Standard
Microsystems' product. Could this be an external hub?
Thanks for the help. Much appreciated.
John.
