Is there any way in XP that I can tell from the software,
device manager, driver or similar whether a particular
device is currently being addressed in USB 2.0 mode?

Thanks, David

Click to expand...

If you have Intel based USB controller:
Open Device manager, select View devices by connection.
Expand the Intel xxxx USB 2.0 Enhanced Host controller.
Find the USB Root hub attached to the above.
if your device is attached immediately to this Root hub, it should work in
the High speed mode.
Otherwise, if it is attahed to any of Intel xxx USB Universal host
controllers,
it works in 1.1 mode.

If your device is attached to external hub, or the host controller
is not Intel, you need some utility that displays USB info.
