New virtual device created every time keyszer starts?

[RedBearAK]

I just looked at dmesg | grep -i keyboard and saw something that seems like maybe shouldn't be happening. It looks like keyszer is creating a new device for the virtual keyboard every time I quit and restart it.

Yep.

I have no idea if this is harmful in anyway. Just seems kind of unnecessary.

I don't see any harm if the old one is gone... it's just a sequential id number...

The full path is /sys/devices/virtual/input/*. Looks like there are a couple of other things creating these virtual input devices. Something called "Acer WMI hotkeys" and a pair of Bluetooth headphones. That's why the numbers aren't always sequential.

Seems there are no old ones. I guess this is just a natural process with Linux.
