You can check your motherboard or system specs to see if it has 1.1 or 2.0 on-board. As far as I know all the motherboard ports are the same speed. It'd be silly for them to have both types when 2.0 ports can accomodate 1.1 devices.

Maybe, like with my old HP, you've got 1.1 ports on the motherboard and have added a 2.0 PCI card. In that case you've got both types. My printer is connected to one of the 1.1 ports and every time I turn it on I too get that message about how it'd run faster on a 2.0 port.

You can check in device manager under 'universal serial bus controllers' to see what you have. A line that reads 'USB enhanced host controller' means you have 2.0.

On mine for example, device manager shows:

Intel 82801AA USB universal host controller

for the on-board 1.1 ports and

NEC PCI to USB enhanced host controller

for the 2.0 ports on the card. There's other stuff showing there too but that's what ID's the port speeds.

If you're connecting your 2.0 hub to a 1.1 motherboard port then I'm sure anything connected to the hub is running at 1.1.

Oh and device manager isn't going to show each individual USB port so don't be concerned when you don't see separate entries there for each port.

Device information part of control panel, show hidden devices.

I'd suspect that if it only shows 1.1 then there is some issue with driver maybe? You might have a hub in between.

A Pit Bull is like a gun you can pet. And there is no safety on it.

From what utility or diagnostic are you getting that information?

My computer pops up the message that this device could run faster on a 2.0 port> I didn't know I had anything but 2.0. I have a hub but its suppose to be 2.0 also.

I have a enhanced controller and my hub even shows as a 2.0 hub. But I still get the message it could run faster if I hooked up to a 2.0 port??? I check the device manager the main usb and the hub are both 2.0

When you have installed Windows from scratch, if the mboard has USB controllers and they are enabled in the mboard's bios, the support for USB 1.x has been installed in Windows before Setup has finished, for all Windows versions 98 and up (Win 95 versions OSR2 or later, ONLY, support USB 1.x, and even then support for it is often not installed automatically).

However, if your mboard DOES support USB 2.0, if the USB 2.0 support IS enabled in the mboard's bios (that's always the default setting)......

- XP must have SP1 or later Windows updates installed in it, in order for it to have the built in support for USB 2.0

- the USB 2.0 support Windows has built into it is NOT installed for the USB controllers until AFTER you have loaded the main chipset drivers for the mboard (for any Windows version, 2000 and up).

After the USB 2.0 support has been installed, the USB 2.0 controller support is shown in Device Manager - USB controllers as for one or more Enhanced controllers, and one or more Root Hub shows more than three available USB ports (those are for the USB 2.0 support) .


XP doesn't have the drivers built in for most things that first came out after XP was first released, circa 2001, and it doesn't have some of the drivers built in for things made before that.

Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.

"Oh and device manager isn't going to show each individual USB port so don't be concerned when you don't see separate entries there for each port."

It does show how many total ports you have and whether or not something is connected to it / them.
(You can't actually use all of the USB ports unless all USB headers on the mboard are connected by wiring to physical USB ports.)

All USB 2.0 controllers also have backwards compatible support for USB 1.1 specs - what you see in Device Manager under USB controllers shows support for both, after the USB 2.0 support has been actually installed.

On modern mboards (since about 2004) ....
- all USB ports support USB 2.0 (recent mboards may have ones that support USB 3.0 too).
- the total number of USB ports supporting USB 1.1 = the total number of USB ports supporting USB 2.0 - they are the same ports, supporting both standards, available by them being built into the mboard physical USB ports, or being ports connected by wiring adapters to mboard headers for physical ports not built into the mboard itself.

For each Root Hub, double click on it and click on the Power tab
Root Hubs for USB 1.1 support usually have 2 ports available, or may have 1 or 3 ports available, never more than 3 - there are more of them.
Root Hubs for USB 2.0 support have more than 3 ports available - there are fewer of them.

If something is connected to a Root Hub, a device is listed there under Power and how much current it is rated to draw.

Devices that DO NOT specify to Windows that they work better if they have USB 2.0 support are ONLY listed under Power in the Root Hubs for USB 1.1 support. E.g. corded keyboards, corded mice.

Devices that DO specify to Windows that they work better if they have USB 2.0 support are ONLY listed under Power in the Root Hubs for USB 2.0 support. E.g. most flash drives, most memory card readers, most printers.

How many devices are connected to the hub? Try just one and see if you get the message.

Also, temporarily remove the hub and connect one of the devices that give that message to a 2.0 port. Then see if you get the message. I'm thinking either the hub isn't working at a full 2.0 or XP is defaulting to seeing it as 1.1.

I will get my MB CD out and make sure I have all the proper drivers installed again> don't think that's whats causing it.

If your mboard supports USB 2.0, and if SP1 or later updates have been installed in Windows (some XP CDs have no SP updates at all), the only other thing it could be is the USB 2.0 support is not enabled in the bios - that IS enabled in default bios settings.
