Thanks, but it isn't that.
Even with it, mouse works on random, after resume from S3.

But what I did figured out, looking kernel msgs on console, just after 
resume, is that IF I see >1 of this:
--
uhub_reattach_port: port 1 reset failed, error=USB_ERR_TIMEOUT
uhub_reattach_port: device problem (USB_ERR_TIMEOUT), disabling port 1
--

Mouse won't work unless I unplug/plug it's USB receiver
