Specifically, this cable configuration doesn't let either side know it is supposed to be a host. On the IOIO, you can work around this problem by moving the switch to the "H" position (force host), but you'll never be able to get the phone into host mode this way to test what might be a solution to your problem. > Perhaps you are talking about that cable I originally asked you about > which splits 1 male into 2 female: one USB and one microUSB? > I suspect this too has a physical splicing of the wires so again there is > no intrinsic direction? > If you buy what's called an "OTG cable" such as this <https://www.amazon.com/UGREEN-Adapter-Female-Samsung-Android/dp/B00N9S9Z0G/ref=sr_1_5?ie=UTF8&qid=1508608674&sr=8-5&keywords=usb+otg+cable> + a standard USB A-to-micro-B cable and plug them together you'd get the cable that you need, which can be used in either direction. > > My brother says that he can tell if the board is "working" because he gets > a message asking something about the IOIO, permission of some sort. > With the new phones (all of them), he sees no messages, no sign of life. > If you can explain exactly what to test, I can have him give it a try. > First thing I would test is have the phone be the host, by using the cable I described and flipping the direction.
