Our Inspire has one slave controller and we use Samsung galaxy on the master and iPhone 5 on the slave. The iPhone will not connect or even charge from the slave, andthe Samsung will charge but not connect. Both phones still work with the master. The flyer, controllers and batteries have all been updated but there is still the same issue with the slave. I think it could be a physical problem with the slave USB port, but we have only flown in dual controller mode maybe ten times. Any advice?
