I had the same problem with my A1200 Tower. In my case, the Cocolino was suspended from the top DB9 mouse port and because of the additional size of the USB/PS2 adapter it protruded too much (hitting the back of my desk)
In the end, I used DB9 extension cable so I could position the Cocolino at the bottom of the tower and consequently it wasn't precariously protruding. As an alternative, I suppose I could have used a Micromys instead because they are cable based.
