Same story here : my kernel autosuspends all usb ports after boot if
no device is connected, but connecting a mouse afterwards doesn't
unsuspend the port.

The good news is, with powertop 2 I have a nice GUI to work around
that : I just go to the "Tunables" tab and switch off autosuspend for
the relevant port. So thanks for the workaround, while we wait for
devices with proper autosuspend support.
