Windows uninstalls device driver on shutdown

This was not a complete solution to the problem, which continues to occur: the symptom
is that the PCI Card drivers have to be reinstalled on some (though not all) bootups.
I have, however, now tracked down part of the cause of this problem. The PCI Card
requires reinstalling on some (but not all) reboots because the two device driver
files which it needs (ousb2hub.sys and ousbehci.sys) have been deleted from
the folder "C:\Windows\System32\Drivers".
It seems to be the case that something is activating an uninstall routine,
which is consequently deleting those two drivers during the Windows close down, or
during the restart. But not on every occasion.
Can anyone suggest why this might occur?
I am using a PCI Card with five USB 2.0 ports on it, that has an NEC chipset. The
software driver files for the device are from OrangeWare Corporation. I have tried
several different versions of the OrangeWare software, versions both with and without
the GUID format in the .INF file, but the problem is experienced with all of them.
It might be significant that the .INF file (OUSB2.INF) copies itself to C:\Windows\INF
as oem3.inf and that at one point my broadband modem's installation over-wrote that
file; and now the OrangeWare .INF copies itself to C:\Windows\INF as oem4.inf
Some versions of the OrangeWare software copy OUSB2.INF to C:\Windows\INF\Other as
OWCousb2.inf instead.
Those are the only .INF files which the installation routine installs. What might
cause Windows ME to run an uninstall routine contained in either of those files during
a reboot?
