Log message:
uhidev(4) does apply the SET_IDLE request to all its child drivers
today. This doesn't seem to be right, since SET_IDLE limits the
reporting frequency for interrupt IN endpoints, normally only required
on keyboard and mouse-like input devices. We noticed recently that
other device types, like e.g. the Cyrus soundKey uaudio(4), will stall
after the SET_IDLE request has been issued.
Therefore we move the SET_IDLE request only to the uhidev(4) child
drivers which seem to require this request. Those we have identified
to be; ukbd(4), ums(4), umstc(4), umt(4), utpms(4), and uwacom(4).
