The driver uses the ctrl value passed in as a bool to determine whether to enable auto-exposure, but the auto-exposure setting is defined as an enum where AUTO has a value of 0 and MANUAL has a value of 1. This leads to a reversed logic where if you send in AUTO, it actually sets manual exposure and vice-versa.
