Dear Stefan Roese,

Indeed. I wonder which arguments the hardware designer has to defend
such an implementation.

Agreed. Eventually the READ ID could / should be combined with the
8/16 bit test, at least for this specific device ID.

Um... what does the Linux kernel code do in this case?

Best regards,
