Jeff Roberts (aka USBMan) explains how to check for high speed USB 2.0 support:
Here’s the screenshot-by-screenshot way of getting there.
If your Device Manager shows an ENHANCED USB Host Controller, the system has High Speed USB (USB 2.0) capability.
Types of High Speed USB (USB 2.0) Host Controllers
- Intel Enhanced
- SiS Enhanced
- VIA Enhanced
- ALi Enhanced
- Standard Enhanced
- NEC Enhanced
The system shown has onboard Intel High Speed USB (USB 2.0) with an NEC High Speed USB (USB 2.0) PCI card installed.
The key word is ENHANCED. If you have an ENHANCED USB Host Controller then you have High Speed USB (USB 2.0)
All other types are USB v.1.1
The difference between v.1.0 and v.1.1 is explained here.

Thank you for the informative article on “How to Check for High Speed USB (USB 2.0) Support”.
Further on this subject:
How can one differentiate which USB port on the computer is 2.0 or 1.0.?
And, is there a quick way to test the throughput of the various ports?

1) They will all be the same unless someone has added a PCI card with USB ports to the computer.
2) I’m sure there is, but I don’t know it. Try Google - maybe search for something like USB speed test?
