OK - no point in attempting the impossible. Pretty brittle
and inflexible of MS to do things that way, but that seems
to be their style at times.

I created the .inf file and installed libusb0.sys, and yes,
the device now appears in testlibusb.exe output.

Can I hope that if the manufacturers USB driver is installed
over the top, that the filter driver will take over
for my application ?

(Thanks for helping sort my problems out.)
