Yes. The mouse is not disconnect, if I right click it turn its lights on and works as long as I don’t stop using it for a period longer than a few seconds (less than 10 seconds). It really seems to be some kind of energy saving. This “saving energy” only stops when I unplug and plug it again.
Still googling around, found something about mouse autosuspend options here:
The latter seems to have a real solution but I did not tried yet (more details in the link!):
" Ubuntu 14.04 to 15.04
Edit the /etc/default/grub file and change the GRUB_CMDLINE_LINUX_DEFAULT line to add the usbcore.autosuspend=-1 option:
GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash usbcore.autosuspend=-1”
Note that quit splash were already present options. So keep other options you have too.
After save the file, update grub:
Now check autosuspend value:
And it should display -1.
Ubuntu 15.10 and above
The procedure is the same, but the param to change is autosuspend_delay_ms (instead of autosuspend)."
