I have a Logitech G203
I have had it for a while and for the past couple of months I have had this issue where it disconnects and reconnects instantly, but often it disconnects and doesn't reconnect back unless I restart the PC. I could deal with it disconnecting and reconnecting but I don't want to restart the PC when it just doesn't work anymore. It happens more often when I'm playing games so maybe it has something to do with fullscreen applications.
I have tried changing the USB port, I have tried reinstalling drivers, and I have tried the USB root hub power management where you don't allow the computer to turn off the device to save power
