"This device can perform faster if..."

Frequently, such as when I turn my printer on, I get the a popup message:

"This device can perform faster if it is connected to a USB 2.0 port...."

-followed (after the advice to click the box) by a long list of USB ports.

I have, however, not the foggiest about what to do with that info.

--Anybody?

Your printer's USB cable must be connected to an old USB 1.1 port probably built-in to your computer.

The message is saying that you would get faster speeds if you connected the printer to a USB 2.0 socket. Have you got a USB 2.0 Hub PCI card on your computer at all? Usually at the bottom of the back panel. Or possibly at the front of the PC?

Right-click on My Computer then click on Properties>Hardware>Device Manager and then on the + sign by Universal Serial Bus controllers - if you then see the word Enhanced anywhere in the list then that means that you do have USB2 capability.

If you do not see the word enhanced you need to get a PCI USB2 card, usually with 4 USB Ports on it - you will then be able to take advantage of the faster USB2 speeds.

The message occasionally turns up when a USB 2 device is connected to USB 2 ports, but a cheap or old cable is used to connect them.

If the ports are USB2, as Technotiger says, then try changing the cable.

Also, some front USB ports in cheaper cases are unable to support USB 2. Try a different port on the back of the computer.

I get the same when connecting my card reader to a front USB2 socket. I assume it is a false report on mine.
I do backups to an external from the same socket--no problems.

All good advice above, but one final point...

If you're happy with the speed that the printer is working, and don't want to be bothered with fitting a USB2 PCI card, there's no reason to worry about the report you're getting. You're not harming anything if you continue to use your printer as it is now.

Hi folks, and thanks for all the input.

I've got a bang-up-to-date system with a Pentium P5 Mobo (with built-in USB 2.0) AND an added USB 2.0 adapter card for more 2.0 sockets.

What I don't know is if my Cable is 2.0. That hadn't occurred to me--but:

how does anyone tell the difference, when there are no markings?

(Definitely not happy with the speed--output of first page is a drag!)

I should add...

my BIOS is set to USB.2.0 with the USB 2.0 controller enabled.

Could it be my USB 2.0 PCI Host controller is not working? (Why is it listed twice?)

Is that info any use?
