Years ago i had same problem with Mi5. The solution was to disable Windows signature verification to install correct USB drivers for Mi5 phone. After that PC regocnized Mi5 in fastboot mode.
Found this in xda oneplus forum today:
OK. I disabled signature verification... I see the yellow mark Android under "other devices"... what drivers do I point it to? It won't accept the ones I d/led from Xiaomi.
