As you move forward with this across the devicescape, how are you
going to selectively enable devices to apply autosuspend to? Is this
done by a whitelisting of specific device ids? Or is this going to be
done based on a detected set of capabilities and then pruning that
back with a blacklist?

I've got some exotic homebrew usb equipment that I'm going to have to
troubleshoot on my own, so it would be useful to know how you are
going to slice the device space so I can figure out which devices
should and should not be affected..eventually.
