Hi Alan,

it definitely is, but with autosuspend defaulting to off, and possibility 
of whitelisting known-good keyboards, we (or HAL, respectively) can still 
turn autosupend on those that are known to work properly, and still save 
some power on some systems.

Unfortunately, I vaguely remember that some keyboards exposed the 
behaviors only when connected to certain HCI controllers, so building the 
whitelist might not be completely trivial.
