TODO: how does the multitap check if a controller is connected? does it ask for the
controller status of each subport? how does this work exactly?
currently, there is a small problem in some specific controller config which seems to
lose track of one controller. E.g. if I put multitap in port2 with inserted joy1, joy2 and joy4
it does not see joy4 controller, but if I put joy1, joy2, joy4 and joy5 it sees
all four of them. The same happens if I skip controllers with id = 0xff...
how did a real unit behave in this case?
