Hi All,
I need to disable or enable one of the 2 interfaces
present on a USB audio device, so the unsed interface
is not visible or available in the windows mixer. What
I'm using now is the function
IoSetDeviceInterfaceState() to enable or disable the
right interface, but it seems to be working only in
winXP and win2K. In win98 or winME the windows mixer
behaves wierdly. Does anyone know of a another way of
disabling an interface or am I missing some other
function that should be called in combination of the
IoSetDeviceInterfaceState() function.
Thanks all in advance.
Martin
