Windows 2000 / Windows XP / Windows SBS 2003: How can I
tell whether the USB ports on my system are 1.1 or 2.0?
Nothing I've looked at in Device Manager or anywhere else
actually seems to say.

Thanks!
 
Enhanced means USB 2.0

Click to expand...

1) RTFM (for the system or motherboard). It will state what they're
supposed to be.

2) Look up your board on the manufacturer's site.

3) If all updates (including all Windows SPs and chipset drivers for your
motherboard) are installed, then USB2 ports can be recognised, in Device
Manager, by the word 'enhanced'.
 
So these would be USB 1.1?

- Standard OpenHCD USB Host Controller
- Standard Universal PCI to USB Host Controller

and this would be USB 2.0?

- Standard Enhanced PCI to USB Host Controller

What if a system shows 5 "USB root hubs" and 5 "host
controllers", but only one of the controllers
says "enhanced"? Do I have 4 USB 1.1 ports and 1 USB 2.0
port? (That particular box actually has 3 pairs of USB
outlets.)

Thanks again!
 
I'm a big believer in RTFM myself, but in this case I
didn't get a FM, just a sheet of installation
instructions. But I hadn't thought of checking the
manufacturer's website; that told me the bad news, that
the board we bought just a month ago only supports USB 1.1.

Thanks!
 
Don't forget that you can buy a PCI card that will give you USB 2.0
ports. I have one which adds two at the rear and has a front panel with
three USB 2.0 ports (hub).

You can buy a card that has USB 2.0 and Firewire.

If you did not install any add in boards for USB 2.0, and your computer
shows the "enhanced" driver in USB, it can be assumed that the ports that
came with your computer are USB 2.0 ports. If they were not, the enhanced
driver would not install. The ports must be there for the detection/install
process to work.
