That is why it is never a good idea to install Windows Update drivers.
It is curious as I have seen many many posts where people have been
having problems with their USB Mice and SP2. Guess we'll have to wait
for the flood of new drivers that should be coming out in the near
future that should fix any of the problems introduced by SP2.

All USB ports are v2.0.

I tried your solution, deleted all USB drivers in device manager, restarted,
enabled USB2.0 support in BIOS, load windows, systems auto-installed usb
drivers, until it reached USB mouse, it prompted me to install driver, so i
clicked on next and after then computer restarted again, like before.

So, I suspected it must be the mouse driver, so I choose last known good
configuration and i skip the mouse driver, and everything works. Then I
manually select the mouse driver, and things works like charm now.

I must stress here that the mouse driver that caused problem was from
Windows Update website. Silly, isn't it?

Thanks dude.


Question: Is all your USB ports version2.0 or is only one or two? If the
port controller is an Enhanced USB port (2.0), the motherboard should
report
this to Windows XP and XP should address it as such. First, check with
motherboard manufacturer and see if a bios update is available.

Try this:
Leave your external drive off.
Enable USB2.0 in the bios.
Uninstall any USB2.0 drivers you installed.
Reboot.
Let Windows completely boot.
Turn your external drive on and see what kind of transfer speed you get
copying and writing a file to it.
With SP1 and SP2 you should not need to install USB2.0 drivers unless it
is
for an add-in card or if the specific motherboard manufacturer states that
it is needed even with SP1 and 2.


I recently installed SP2 in my computer and it failed to start after
restarted, not even on safemode or safemode with command prompt.

After many attempts to fix, finally i found out it happened because of my
BIOS USB2.0 controller. And my computer has driver from Intel installed.

I formatted my computer (very sadly), and reinstall xp with SP2, before
installing hardware drivers. I noticed my USB2.0 not installed, so I
installed it with file downloaded from Intel website. All went smooth for
other devices until it reached driver for USB2.0, computer suddently
restart. I managed to get the computer up again after selected 'Last
Known
Good Configuration'. This kept on happenning everytime I install the

driver.

Feeling giving up, I went to BIOS setting and turn off the USB2.0
support,
and now everything went smooth. However, my USB external HDD runs very
slowly.

It's a wonder, too, that even after service pack 1a, I still need to

install

USB2.0 driver manually. I read somewhere saying SP1a would turn it on,
but
it didn't.

Any solution to this matter?

Thanks all.
