If "enhanced" is present, then on 99% of the computers out there this means
that ALL the ports are USB 2.0.

99.999% of the time if it says USB 2.0 for any one of them, ALL OF THEM ARE
2.0.
Thanks,

Yes, there are expansion cards that will add USB 2.0 ports to an older system.
In fact I've done exactly that on one of my older systems.

Computer has one USB 2.0 controller and three (or five, if you enable all the ports) USB companion controllers that report themselves as USB 1.1 devices. If you plug a USB 2.0 device into any port, the device functions at USB 2.0 speeds; the controller handles the logic internally. USB controllers from different vendors might not report ports in the same way and might not indicate that all the ports are USB 2.0 capable, but each should have the same functionality.

If all the USB ports are 2.0, according to your comment above,if just one of them says "enhanced" then why do I keep getting the message that my device could work faster on a hi-speed port? Are you saying that all 6 usb ports on my computer are hi-speed even though only one says enhanced? If you are not saying this, how can I tell which one is the hi-speed one?
Thanks!

Yes, I've said it repeatedly: on *most* computers (like 99%)
even if "enhanced" shows up only once, then ALL USB ports
are 2.0.
For that other 1% I don't know of a way, offhand, to tell
the difference, other than simply trying your device in all
the ports - or checking your computer's documentation. The
only time I've ever seen this is if the computer itself only
supports 1.1, and you add a USB 2.0 expansion card ... then
it's fairly obvious that the ports on the card are 2.0 and
the others are not.
More likely is that there's something else - like perhaps
you're connecting through a USB hub that doesn't support
2.0.

Possible solution to get rid of message... Click on properties of the "enhanced" USB in device manager. Then click on "Advanced" tab... at the bottom will be an option to ignore usb errors... choose that and hit ok. That should get rid of the message. Hope that helps.
Posted by: Kendrick at April 7, 2008 7:38 PMIn the example regarding identifying whether or not one has USB 2.0, the picture also shows four listings for universal host controllers. Does this mean that some (four) of the USB ports are 1.1 and one is 2.0?
