load lower filter in Win 98

I would like to have an inf example in order to load a lower filter in
Windows 98. I tried it and the system doesn’t load my filter driver.
Could I load a lower filter driver in a device stack having .vxd
drivers?

I tried in a USB device stack to load a lower filter and it works very
well. But when I load the lower filter in a stack having .vxd files…
it doesn’t work.

It’s why I would like to have some hint about that.

Regards
