About 3 weeks ago (may 2008) I found that one of our pc's had lost its
usb functionality. Xp pro, installed and running for 3 years.
It has a ps/2 keyboard, ms usb optical mouse and occasionally has 2
different types of samsung flash based mp3 players connected.
After much fiddling I declared the usb controller dead (pc was 8 years
old) and swapped monitor, keyboards, mouse etc to another box running xp
pro fresh install.
3 weeks later I have the very same problem on this box.
That particular box had run xp pro for 3 years without a hitch with a
gaming usb keyboard and gaming usb mouse and a usb external drive with
no problems.
The symptoms (identical on both boxes);
Mouse is found to be frozen at log on to xp.
Inspection of device manager shows following under
universal serial bus controllers:
standard enhance pci to usb host controller
standard openhcd usb host controller
both with a black exclamation mark on a yellow back ground
right clicking either brings up a code 41 error message.
I have tried countess attempts at uninstalling them, rebooting, scanning
for hardware changes.
Updating drivers results in a message saying the driver is fine.
Uninstalled sp3 back to sp2.
Checked bios for usb settings enabled
Changed bios setting to enable/disbale pnp OS.
Added a registery key 'usb' with a 'dword value of
DisableSelectiveSuspend set to '1'
Also looked in registery for key that has 'filters' (?) but it did not
appear to exist.
I am now baffled.
Please help...
