Default USB Device Problem?

I continue to get the following message regarding a USB device:

---------------------------
This device can perform faster.
This USB device can perform faster if you connect it to a HI-Speed USB
2.0 Port. For a list of available ports, click below.
----------------------------------

I click below and it shows my USB2 ports, but no where does it tell me
the device that it is referring to! How can I determine the device in
question?

I have an 8 port USB2 Controller. All my USB devices are plugged into
it.

All my devices work, but I keep getting this message. If the message
would identify the device it has a problem with, then I could research
it. I checked in Device Manager and the port is listed as ""Intel(R)
82801EB USB2 Enhanced Host Controller 24DD".

Then message is random and does not come up all the time, but every now and then - about
twice a day.

Any insights are appreciated.

Your 8-port (do you really mean 7-port?) USB hub is your problem. Hubs
are terribly unreliable, it's better to attach devices directly to a USB
port on the computer rather than through hubs. Hubs are okay for a few
low-priority devices that don't really require high speeds, such as
keyboards and mice and stuff. But you should try to attach storage
devices like flash drives and hard drives directly to the computer on
their own separate ports.

He's referring to the ICH5 Southbridge of his motherboard, and the
logic block inside there associated with USB2. That is the

Intel(R) 82801EB USB2 Enhanced Host Controller 24DD

that controls USB2 operation on up to eight USB connectors on
the motherboard.

And I don't have a clue why it would be doing that, unless
there are USB bus resets, followed by an incorrect negotiation.
It still implies a hardware malfunction, as the software and
hardware would be attempting to run at USB2 rates, but for whatever
reason, the attempt fails and the hardware connected to the port ends
up at USB 1.1 rates. So you'd have a bus reset (which is a normal
part of the protocol, but needs an event to kick it off), followed
by a failed negotiation.

Even if you had a copy of UVCVIEW or equivalent, I doubt it would
tell you anything.

There was at least one motherboard, that had a "drive strength" setting
in the BIOS for the USB ports. Changing that, affects the current flow in
USB2 mode. But such a setting hasn't been made available in years, implying
tuning it is not necessary. On the motherboard I spotted that setting on,
the hardware never needed any adjustment of that value, and worked as well
as any other motherboard with USB2 I've got.

I'd be more concerned, if a USB2 PCI card was added to the PC, and the
symptoms continued. Using a USB2 PCI card, allows testing with another
USB chip. If it cures the problem, then you'd know there was something
about the motherboard and its ICH5, which was at fault.

Since the ICH5 has the "latchup failure" problem associated with the
USB ports, I'd insert and use a USB2 PCI card anyway, just to protect
the motherboard. It would be hard to find a nice replacement motherboard,
if the ICH5 burns up.

(ICH5 after failure related to USB ports... That's a burn mark.)

Thank you both for your comments/input.
I just wish it would tell me which one it is referring to!
