How do I tell if a device is doing USB 3.0 and not downgraded to USB 2.0 for some reason?

Question
For example, if I plug a USB 3.0 device and find that the I/O performance is rather slow, how do I check whether it's because the device is actually doing USB 2.0 (even though I'm using a USB 3.0 cable, connected to a USB 3.0 port on my MacBook Pro).
