I have also checked this with the board manufacturer and they claim there is
no problem with the hardware. Maybe I was wrong to use the word switch. Let
me clarify this connection: There's one PS/2 mouse & keyboard 6-pin mini-din
connector on the board. Imagine this as a V-shaped connection. On the board
side there is one connector, on the mouse & keyboard side there are 2 cables
each ending with a dedicated PS/2 connector for mouse and keyboard.
This problem occurs especially when I run a debug image. With a release
build, I seldom get this error.
