I'm trying to take the first step to establish a connection with an iPhone using the Lightning port. I'm using the Lightning A male connector body, which I believe should set the iPhone to be a USB host. I'm hoping that the iPhone will start to enumerate my USB device, but I'm receiving practically nothing from the phone.
Twice I've seen a short invalid packet of about 16 bits, but that's very rare. What's the first step to take? Do I need some magic pull-up or pull-down somewhere or am I using the wrong connector body? Should I use some other Lightning connector body? I have samples of the four basic types. And yes, I'm an MFi member, hopefully not the only one here.
