Comment(by sunrise1):
While I have no objection to this ticket, I believe that a more agressive
resume will not be enough to dispel an impression of "slow responsiveness"
that a XO user might assert. When my (non-suspended) XO has not had any
keyboard input for a while (and particularly if a task happens to be
running and using 100% of the CPU), I can press a key - then have to wait
much more than 800 msec to see that character appear on the screen.
FWIW, at home I usually run with five or more devices plugged into the
USB. Although I normally haven't used suspend (NM 0.6 doesn't resume my
ethernet connection), when I have tested it I have *not* felt unduly "held
back" by the time the XO takes to re-activate my USB devices. [Rightly or
wrongly, my impression is that what takes time after resume is for the
software to dialogue with the device, not the delay for the port to come
up.]

I'm glad that under 0.83 the software does not appear to be scanning the
content of my "permanent" SD card -- that could take minutes all told. [If
done after a 'resume', such a sc[http://www.tagnice.com nike air yeezy
