USBInfo is probably something you may not need unless you want to benchmark the raw speed of your USB TV tuners, hard drives, flash drives and USB PCI cards. It will tell you if the device is Hi-Speed USB or not. Plus, it reportedly assists you in troubleshooting devices, and displays a topology view of your USB devices. But just for troubleshooting and peeking at your USB bandwidth, the $149 is a bit pricey.
