I have an issue with one machine of mine that is running Ubuntu 16.04.
The key presses start malfunctioning like I'm holding a key down when in reality I have removed my hands completely. The situation can be fixed only by removing the Android device USB connection.
I have tried multiple Android devices and they all have the same issue. I also have several other colleagues with the exact same PC hardware setup and they don't have the issue. Can anyone suggest how I might be able to debug the issue to see what the problem is?
I found the problem. I had a powered 4 port USB hub that my keyboard was plugged in to like this one. When I connected my keyboard directly to the PC the problem goes away.
