SubjectRe: [PATCH] make psaux reconnect adjustable

This is a serious bug in many user-space drivers. PS/2 mouse protocol
was designed to easily re-synchronize (think about transmission errors/
lost bytes).

The fragment of text you reply to is not about the 3-byte PS/2
protocol, but about the 4-byte wheelmouse protocol.
