If thats the case, I kind of suspect that you can use the Cocolino or the switcher, but if you use both you'll have to just accept the problems you're having. The switcher probably is designed to only pass on signals that it thinks a mouse (or joystick) should be sending. Some of the other signals, like the wheel, are probably just being dropped. Probably you need to ask the switcher manufacturer if that's the case and encourage them to fix it in the next design revision.
