I am making an upper filter driver for an USB audio. For a test, I made
a really simple one. In this filter, I couldn't get an
IOCTL_KS_READ_STREAM, but I can see IOCTL_KS_PROPERTY and
IOCTL_KS_WRITE_STREAM. What happened? I added my filter driver in
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB\Vid_077d&Pid_07af&
MI_00]
"UpperFilters"="MyUpperfilter"
Below is my registry key when I connected my device in a machine.
