On what?

By checking the chipset, or via the Device manager in Windows :-)

OK. So what do I look for in the Device Manager that would tell me?? I've
already looked, and nothing actually says "USB 1.0" or "USB 2.0."

2.0 = enhanced. Otherwise it's 1.1

A non-technical way is to plug a device you know is designed for USB 2.0
into your computer (such as a modern USB memory stick). If Windows
complains about a "HI-SPEED device plugged into a non HI-SPEED port",
you have USB 1.0. If there is no message, USB 2.0.

I've not seen that with a USB2 memory stick or a USB2 drive caddy, so I
wouldn't bank on it.

Look in device manager and google for whatever USB chipset is reported, or
measure throughput of a USB drive using perfmon, or look in the motherboard
manual, or look at the specs on the manufacturers website.

Meh. It happens to me all the time with my computer at work.

I'm curious - as I work with a variety of kit and haven't seen this - I
suspect that it's something particular to either the device driver or the
chipset driver. What devices are you using? I would guess that if the device
is something that absolutely requires USB2 bandwith - then it would be
sensible for the driver to complain.
