Last sentence is completely redundant. You are not supposed to reference
drivers here. I even EXPLICITLY marked this with BOLD font (as a common
mistake) in DTS101 speech.

Explain why devices are or are not compatible. You claim they are
compatible, but driver still treats them partially incompatible.
