### Bug description
The Razer Viper Mini mouse has 2 side buttons (Button 4 and Button 5). One of the buttons, specifically Button 4, does not work.
Installing openrazer drivers also does not give any result.
The button starts working if you enter this command:
echo -n -e "\x03\x00" > /sys/bus/hid/drivers/razermouse/*1532:008A*/device_mode
I wrote about this problem in the openrazer repository, but at some point they stopped answering me about what else I could try.
