I want to turn off the "This device can perform better if you use a high
speed port. Click here for a list of high speed ports." message that pops up
on the status bar every time I turn on my laptop. It doesn't have any high
speed ports and will never have them.

How can I turn this notification off? Any registry settings that can be
changed?

Right click on "My Computer", select "Properties", select "Device Manager",
expand "Universal Serial Bus controllers", right click on "USB Universal
Host Controller", select "Properties", then the "Advanced" tab, put a tick
on the "Don't tell me about USB errors" then click "OK". You may have to do
it for all the host controllers.

Are you sure about that? This message should only appear if you have high
speed ports available AND you connect a USB2 device to a USB1 port
(including connecting it to a USB2 port where reliable communication cannot
be achieved and it reverts to USB1 operation). If you don't have high speed
ports, then this error message should not be issued. It can be that the
wrong USB2 driver is installed or the root port or USB2 root hub has failed.

I myself bought a laptop around 3 years ago that was not advertised as USB2.
And indeed it only worked at USB1 speeds (but no error message indicating
otherwise), so I was as sure as you probably are now. However, upgrading
Windows XP to SP2 loaded the USB2 drivers and suddenly, I had a USB2 laptop.
Was I ever surprised.

Open up device manager and scroll down to the USB devices (at the bottom of
the list) and expand. There should be a number of Root ports and root hubs.
If any of these are shown as 'Enhanced' then you have high speed ports.
However, the absence of that label proves nothing. Open up each root hub in
turn and select properties and the Power tab. If there are 2 ports shown
for each one, all well and good. But if you come across one with more than
2 ports (and it will usually be the bottom one), then these are USB2 root
hubs. With a USB2 system, the total ports on the root hubs is double the
number of physical port connectors (but all the pysical ports are not always
brought out to connectors on the outside of the casing, so this is not a
reliable guide).

Note that if the drivers are missing or the wrong drivers are installed,
then the USB2 ports and hubs should show as disabled or under 'unknown
devices'.

Open the Device Manager, under "USB Controller" you find
items like 'USB host controller'. Right-click, select
Properties. The tab 'Advanced' has a checkbox "Don't show
USB errors".
But this deactivates all USB error ballons.
