Hi Michael,
I think SVN is more up to date. Just give it some time and CVS will be updated
aswell.

Not yet. Probably I will add some simple power management support after
new-year. Be aware that many USB devices have broken suspend/resume support
and can fail, so leaving the power on is sometimes better.
When no devices are attached, I am going to add support so that the HC is
turned off. That will save some power.
Remember that suspend/resume cycles introduce extra latency getting the system
up and running again.
