USB Enhanced Port

Windows Vista Home Premium SP1 64 bit
Device manager shows these ports.
Anybody know how to tell which is the "Enhanced" port?

Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C8
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27C9
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CA
Intel(R) 82801G (ICH7 Family) USB Universal Host Controller - 27CB
**Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC**

Thanks,
BChat

Since your hardware is fairly new, I'm sure all ports on your mobo are USB2


USB1 mobo's were dropped a number of years ago...
probably before Vista even came out

Thanks philo,

Is the ENHANCED controller a certain USB port, or does it refer to all of
them? The reason I ask is when I was installing a scanner, it said it might
work better if it was in an Enhanced port. A popup window highlighted
"Intel(R) 82801G (ICH7 Family) USB2 Enhanced Host Controller - 27CC" and I
have no clue what USB port it is on the machine.

We don't have the manual here to tell you which one (physically) is an
enhanced port. Conversely - you DO have the manual!

Thanks Richard,

I know so little about the USB system I couldn't even ask a cool question
;-) - off to "RTM"

I RTM'd - it told me nothing - zilch - zero - nada.
Must be a need-to-know item and somebody has decided I don't have the need

The short answer: they all are.

The long answer:

Universal Host Controllers are USB 1.1, at speeds of 1.5Mb or 12 Mb. They
control 2 ports. Having 4 of them should indicate that you have 8 ports.
Some may be used by built-in devices such as memory card readers.

Enhanced Host Controllers are USB 2.0, capable of speeds of 480Mb. They
control 8 ports. They share the same 8 ports of the Universal Host
Controllers.

You will also see listed 5 USB Root Hubs. 4 of those are 2-port USB 1.1
hubs, the 5th is an 8-port USB 2.0. All of this switches automatically to
whichever controller/hub is needed depending on whether the device is USB
1.1 or 2.0.

Thank you - now I know, and understand USB a lot more.

One easy way to find out is to insert a USB 2.0 flash drive into the ports,
one at a time. If you see a message popping in the system tray, telling you
that you may get faster speed if you use other port... that port is NOT a
USB 2.0
It is an enhanced port (USB 2.0) otherwise.
