"\USB#Vid_8019&Pid_0805&MI_00" is my physical USB equipment, but "\ROOT#MEDIA#0000" is not my equipment. What does this mean? What should I do?

My tip is to check why the driver is loaded. Have you specified your driver for this hardware typ {7a9171d1-69cc-4939-be31-bbb2f4f9e9c5} or NOT changed the id from some sample code.
