[18:49] hi, not sure if this is the right room.. I'm on ubuntu 17.10, gnome-shell 3.26.2, I'm using Logitech USB Optical Mouse and I removed the usb dongle, when I inserted back the mouse is not working. I see it is recognized from dmesg output, but I don't see the device in xinput output.. [18:50] I tried restarting USB service but didn't help.. This happened before and I know restarting the system fixes the problem. But I'm looking for a way to recover usb mouse without restarting the system.. [19:42] just solved the problem.. find the bus number (003) and then generate the string "usb3" then "echo usb3 | sudo tee /sys/bus/usb/drivers/usb/unbind" [19:42] and then echo usb3 | sudo tee /sys/bus/usb/drivers/usb/bind
