To tell USB 1.0 from USB 2.0...
...you have to pay attention to what tree the device appears on.
The Standard OpenHCD USB Host Controller represents USB 1.0 and anything that appears under that heading in USB View's tree display is a USB 1.0 device.
The Standard Enhanced PCI to USB Host Controller represents USB 2.0 and anything that appears under that heading in USB View's tree display is a USB 2.0 device.
Now, one caveate to this explanation is that if use a USB 1.0 hub (as I showed in my example) and then plug a USB 2.0 device into the USB 1.0 Hub, that device will appear in the USB 1.0 tree.
