This SHOULD be appearing in
HKEY_LOCAL_MACHINE \
SYSTEM \
CurrentControlSet \
Control \
DeviceClasses \
{6994ad04-93ef-11d0-a3cc-00a0c9223196}\ (which
is KSCATEGORY_AUDIO)
##?#PCI#VEN_xxxx...\ (depending on your
device ID)
#GLOBAL \
Device Parameters
So, you should see a subkey called MSFEP in there, and 0 within that.
The registry key should be present, even though the device interface has
not yet been enabled.
