Re: Need some help understanding USB Controllers on computer

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

A controller controls 2 ports. The ports are the physical USB connectors on
your computer.

The enhanced controller is the USB 2.0 driver. It enables any and all
capable USB 2.0 controller (Intel specific in your case) to operate at that
speed.

Whether all such USB controllers are of USB 2.0 capability is another matter
on your computer. Some computer/motherboard makers chose to put one USB 2.0
capable controller, and remainder USB 1.1 controller(s). In some cases, a
USB controller connector is on the motherboard for facility for a front
panel connection for 2 USB ports. May be visible in XP, but no
corresponding USB ports for it external to the computer.

Intel(r) 8280 1DB/DBM USB 2.0 Enhanced Host Controller - 24CD
Intel(R) 8280 1DB/DBM USB Enhanced Host Controller - 24C2
Intel(R) 8280 1DB/DBM USB Enhanced Host Controller - 24C4
Intel(R) 8280 1DB/DBM USB Enhanced Host Controller - 24C7

I made a mistake im my origianl post, This should have read:

Intel(r) 8280 1DB/DBM USB 2.0 Enhanced Host Controller - 24CD
Intel(R) 8280 1DB/DBM USB Universal Host Controller - 24C2
Intel(R) 8280 1DB/DBM USB Universal Host Controller - 24C4
Intel(R) 8280 1DB/DBM USB Universal Host Controller - 24C7


Since I only have one Enhanced Host controller, one port and only one port
of my four can be USB 2 at any one time? Or, because I have an Enhanced
controller can all ports can be USB 2?

Why do I have three Universal Host Controllers if all I have is USB 2
capable ports?

Does each port need an individual controller?
