Playing with powertop, I got the following suggestion:
Suggestion: Enable the CONFIG_USB_SUSPEND kernel configuration option. This option will automatically disable UHCI USB when not in use, and may save approximately 1 Watt of power.
Is this something we should do in our kernel? Or what is the risk for this? Will it break automatic access to hot-pluggable devices?
It will _not_ break hotplug. But it'll break all non-compliant devices unless they are in the list list of quirky devices.However, we know that list is incomplete. But we don't know how incomplete. As a compromise, we might change the default to enable it only for devices with drivers in the kernel. That would be a kind of whitelist.
So, what is the best way to move forward? Enable it directly after 10.3 is out so that people using alpha releases can report problems?
