Turn-off Causes Double Install

[Pat]

If I "Restart" my XP SP2 box any number of times and check in Device Manager (showing
Hidden Devices) all is well.

If I do "Turn off" and then startup again then many devices are doubled. These twins are
greyed-out and their properties say "Currently, this hardware device is not connected to
the computer. (Code 45)"

I uninstall both twins (grey and normal) and Restart and the normals return (finding new
hardware and reinstalling messages) and the grey twins are gone.

Restart- still gone.
Turnoff and startup- the twins are back. Repeating the turn off does not create quads etc.

Anyone else seen this behaviour? Anyone know what causes it? I have done a lot of hardware
changes lately and have just added Bluetooth using SP2's own drivers on a Belkin dongle.

Twins ONLY occur in:

Bluetooth Device
Bluetooth Enumerator
The 2 CD_ROM drives
Primary and Secondary IDE Channels
Standard Modem over Bluetooth link
Bluetooth Device PAN network adapter
Bluetooth Device RFCOMM network adapter
USB Universal Host Controllers x5
USB Root Hubs
- out of the full Device Manager list

Thanks for reading all this - I could not work out how to say it briefly!

It's probably some BIOS problem

Well, I have tried:

flashing and resetting the BIOS
Disabling Shadow Volumes
Starting a new profile

but still the same thing - Uninstall "hidden" and visible double entries - restart many
times - OK (no hidden)
Turn off and Startup - hidden double entries return.

It effects IDE, USB, CD, Bluetooth (all I/O?)

Maybe they are supposed to be there. Anyone else got 'em? (Double entries in Device
Manager/View/Hidden)

Hmm... looks like I have been tilting at windmills
Or, rather trying to remove "phantoms" of past installs and uninstalls
This article showing Device Manager error codes seems to cover it - and the phantoms are
now properly invisible!

Hope this might help anyone else bothered by ghosts!
