USB Problem

I am running Windows XP Professional sp2. I get a message that says a device
will run faster with USB 2.0 drivers installed. The device is either a
CD/DVD writer or a protable Hard Drive. I have gone to Device Manager and
tried to Update the drivers but don't seem to have any luck since the same
message appears the next time I attempt to use the devices. The work,
slowly, but they work.

Can someone point me in the correct direction to find a solution to this
problem. I've had it quite a while and would now like to fix it. I've tried
looking through the support pages but don't see what I need or I am too dumb
to recognize it.

Please help me if you can.

Thanks.
 
Go to Start/Run, and type DEVMGMT.MSC , highlight the USB Root Hub device(s),
Action menu, "Uninstall", then restart Windows, to find the device drivers
again automatically.

The message probably really says that it will run faster if you plug it into
a USB2 *port*. It's the port that is referred to.

You need to be sure that your computer has USB2 *ports* with USB 2 drivers
installed, and that you plug those devices into those ports.

You can't install USB2 drivers to make USB1 hardware work faster, but USB2
hardware without correct drivers will run only at USB1 speeds.

These drivers are often found as part of the chipset drivers for the
motherboard.

If your system does not have USB2 ports, get a USB2 card. This may be
around $15, and you will not have to install drivers for it.

If your system is a laptop, you can get a PCMCIA (People Can't Memorise
Computer Industry Acronyms) USB2 card for about the same price. I did.

In my case, the laptop is an IBM T30, which has USB2 on the motherboard,
but it also has a hardware fault that causes it to forget this fact.
Actually, the T30 may be USB1, but later ThinkPads certainly have this
flaw. The $15 card is easier than the motherboard replacement, and (as
it happens) I ended up with a pair of ports whose separation allows me
to plug both my USB2 devices in at the same time - bonus!

I use such a device with my Thinkpad R31. However, you do have to be
careful - you don't get full power on all ports on the card, so if you try
to connect a laptop hard disk using hte 3-headed cable, it will fail. You
have to use the data connector on the USB2 card, and plug the extra power
USB connector into one of the motherboard USB ports.

In this context I'm not much of a "Power user" :-)
I'll avoid plugging my USB Christmas tree into my USB2 adapter (it
performs just as well with USB1). I'll also avoid (if I ever get them)
USB powered heated socks, which probably also perform equally well with
USB1.

Most USB 2.0 drivers are delivered directly from Microsoft XP Servise
Packs. I have yet to see a motherboard manufacturer provide their own
drivers for USB 2.0 port (in XP.)
