USB speeds and external drives

How do I tell what USB speed an external drive is connected at? I've occasionally seen Windows warn me that a device could operate faster if plugged into a different port, but as far as I can tell, that only happens if I plug the drive in after boot. How can I tell what speed the drive is using if it was present at boot? I'm using XP.
 
Check your XP Device Manager. In the "USB" section near the bottom, if you don't see a "USB 2.0 Enhanced Host Controller" entry, then your PC only has USB 1.x ports. Which is likely your situation.

USB 2.0 PCI cards are only $10 or $20.

I do have a USB2 controller, and I suspect all of my ports are USB2 since I only see the warning occasionally (I haven't seen it since uninstalling the libusb driver some software I used to use required), but I'm looking for a way to verify that everything is going at USB2.0 speeds.

The only way I know is to do a file transfer and see what the transfer rate is. The difference between USB 1.0 and 2.0 is hard to miss, since it's a factor of 40x.

If you are getting a warning message saying, "....could operate faster if plugged into a different port...", then something's wrong. That's the message you get when you have plugged a USB 2.0 device into a USB 1.0 port.
