PiKVM v2 (Pi 4) emulated mouse runs away
name: PiKVM v2 (Pi 4) emulated mouse runs away about: When using the emulated mouse on the PiKVM v2 it fails to properly work but works fine with a normal Raspberry Pi install
Describe the bug When using the emulated mouse on the PiKVM v2 it fails to properly work but works fine with a normal Raspberry Pi Desktop install
To reproduce Use a PiKVM v2 and try to use a mouse with PINN
Expected behaviour Mouse should work like a normal Raspberry Pi Desktop
Actual behaviour Mouse randomly moves around
System Add answers to the following questions:
- Which model of Raspberry Pi? e.g. Pi4 with PiKVM v2
- Which version of PINN? Newest
Would you like me to send the parts for you to test with? I can as long as you send them back when done. Thanks!
That's a very kind offer, but maybe we can do some investigation beforehand.
What is the output of the following commands with and without the PiKVM attached?
ls -R /dev/input
lsusb
lsmod
With PiKVM v2 attached:

I do have a USB keyboard attached so I can write via HDMI as well. This still happens without the USB keyboard plugged in.
Am I right in thinking that the PiKVM mouse does follow your movements correctly, but there is an additional drift or random component added to that? Because it looks like the PiKVM is presenting an additional joystick input (js0) which is probably the cause.
