✓ Host does not support PD so does not look for alternate mode devices
✓ Host finds alternate mode device, but does not support this particular device
✓ Alternate mode device presents either an equivalent USB
function and/or USB Billboard Device interface to the USB stack
✓ Billboard Device provides the OS with information about the alternate mode device that it can be use to inform the user that the host does not support the alternate mode
Failure to find an Alternate Mode
Summary
