Looks like quite a few people have issues with that mouse. Googling for
"idVendor=045e, idProduct=0084" brings up several hits with people describing
what you are seeing.
Basically, it looks like the latest firmware on the mouse seems to have some
powersaving functions that don't work properly.
Can you test with a different mouse to see if that one works?
Alternatively, disable USB powersaving:
# for i in /sys/bus/usb/devices/*/power/autosuspend;
do echo 2 > $i;
done
# for foo in /sys/bus/usb/devices/*/power/level;
do echo on > $foo;
done
