[OT] Limiting the use of USB devices on Windows XP

Limiting the use of USB devices on Windows XP

I have a friend who is currently being driven to despair trying to
implement
site IT security.
His brief is to prevent users from adding or removing files to the company
system using removable USB drives

The problem is that there is a decree that users must be able to use
sanctioned company provided USB flash drives (don't ask, we know how
contradictory and stupid this is)

The two commercial solutions : DeviceLock & SecureWave Sanctuary
DeviceControl   both operate using VID & PID from the USB device,
Device
lock allows the use of a white list to even permit certain VID & PID
combinations,

BUT   the daft thing is that the VID & PID used are the ones from the
device
controller, and as 99% of flash drives use the same controller it's
impossible to limit the use to one specific manufacturers Flash drive, and
what's worse is that Devicelock people won't or can't even acknowledge that
a controller IC can have a different VID & PID to the device it's used
in -
Arghhhhh!

We have looked at enumerating VID & PID ourselves but it quickly
becomes
tricky determining which devices are USB flash drives

Has anyone come across this problem or know of a possible solution?

Thanks for your time
