USB 1.1 or 2.0

[craig callinan]

Can anyone tell me how I can determine whether I have USB 2.0 or 1.1? Dell
told me I could find this information in the BIOS. I looked. It's not
there. Can't find it in Device Manager either.

Responding via email would be best.

Thanks,

Craig

If this is Windows, go to the Control Panel, System, Hardware, Device
Manager.

Click on Universal Serial Bus controllers.

Look down the list.

If you see OHCI or Open Host Controller or UHCI or Universal Host
Controller, you have a USB 1.1 controller.

If you see EHCI or Ehnahced Host Controller, you have a USB 2.0 USB
controller. If you see an EHCI controller, you should also see a UHCI or
OHCI controller as well.

Ive wondered about this question too - thanks Marc - I believe the only
differance between 1.1 and 2.0
is that 2.0 has more bandwidth - is this correct ?

From a users point of view, yes (more or less).

But that is like saying the only difference between a Ferrari and a Mac
Truck is the Ferrari goes faster. ;=)
